Learn How to Care for Your Porcupine Puffer Fish Before you Bring Him Home

Porcupine puffers are engaging and intelligent saltwater fish almost as cute as cartoon animals. They usually learn to interact with their human caregivers in odd and engaging ways; some even respond to eye contact by swimming up and begging for food! Their engaging personalities combined with big eyes, chubby cheeks, and silly grins make them adorable pets.

While they get rather large and require a big aquarium, their care is easy compared to that of many saltwater fish. They can handle fluctuations in PH, temperature, and salinity better than many other fish and don't as often go on hunger strike in response to stress. These fish are actually rather sturdy creatures as far as saltwater fish go, so long as you give them proper care. If you maintain a healthy aquarium and feed your pet properly you can enjoy his antics for many years.

Also sometimes called balloonfish or porcupinefish, these fish are slow-moving and easy for divers to catch, making them readily available for purchase and relatively inexpensive compared to most other saltwater fish.

All of these qualities make them very popular in the aquarium trade. This page will give you the basics on how to care for a porcupine puffer. Please research any species of fish you plan to keep as a pet before you buy.

What Is the Minimum Tank Size for a Porcupine Puffer?

The first thing to do before you buy a porcupine puffer is to make sure you have a big enough system to handle his size. They are big and hefty fish that can reach an adult size of well over a foot long. They are also often sloppy eaters who make a lot of waste.

When it comes to aquarium fish, porcupine puffers are like SUVs when it comes to fuel efficiency. They go through a lot of fuel and they create a bunch of pollution.

As with all fish, you should always consider the adult size of the porcupinefish when deciding to put one in your marine aquarium. To stay happy and healthy, his tank should be no smaller than 100 gallons, both so he has room to swim and to allow for enough biological filtration and water volume to handle his waste.

It is also much, much easier to keep a large saltwater fish tank than it is to keep a small saltwater fish tank. The added volume creates greater stability so small changes don't cause big problems nearly as quickly as they do in a smaller aquarium. Bigger is better and extra gallons buy you time to tweak and and make corrections before your fish suffer from them.

Don't bring your new pet home until you have a big, cycled saltwater aquarium to put him into.

How Do You Keep the Tank Clean Even Though They're Messy Eaters...

...and require extra work to keep clean?

Because porcupine puffers create so much waste, be prepared to do a lot of water changes to remove this waste even if you have a plenum or other nitrate removing device in your aquarium. I'd recommend changing no less than 20% of the tank's water weekly to keep up with his waste production.

You can also keep the water cleaner by removing any uneaten food and any visible waste using a tank vacuum to suck it out. If you feed frozen food, be sure to thaw the food thoroughly and discard any water it may have been packed in. The melt water usually contains food juices that will spoil quickly in your display tank. Some aquarists also claim that feeding dry food can create more waste problems as it is not as completely broken down by your fish's digestive tract as fresh or frozen foods are.

This is part of the reason it's a good idea to house your puffer in the largest tank you can manage. A larger water volume dilutes wastes better than a smaller water volume.

I've found the use of a refugium filled with chaetomorpha macroalgae kept on a twenty-four hour light cycle helps a great deal with maintaining high water quality. My Porky's tankmates also enjoy eating the macroalgae that I harvest when it outgrows the hang-on-tank refugium.

Where Can I Buy A Porcupine Puffer?

You can buy porcupine puffers in most pet stores that sell saltwater fish. They can also be bought online, but I do not recommend it due to complications that can occur in shipping.

A Practical Fishkeeping Guide for Keepers of Pufferfish - Learn how to care for your puffer pets

Pufferfish (Practical Fishkeeping)
Pufferfish (Practical Fishkeeping)

Just like the title says, this book is a practical guide to keeping pufferfish written in easy-to-understand language.


Trace Elements are Important to Porcupine Puffer Care.

Porcupine puffers are prone to developing deficiencies or thyroid issues if they they don't get proper levels of trace elements found in seawater. This is yet another reason frequent water changes are important to their health. Frequent water changes help keep the levels of trace elements that are consumed by fish, plants, and invertebrates at the necessary levels. If you also keep corals or rely on macroalgae filtration to minimize the frequency of water changes, it may be a good idea to supplement your tank with iodine per the instructions on whatever iodine supplement you purchase.

Maintaining proper levels of iodine is important for thyroid health in pufferfish.

Supplemental Iodine for Thyroid Health

When added as directed, iodine supplements can help keep your puffer's thyroid healthy. Iodine supplementation is also important to the health of corals and other fish you may keep with him as the iodine in saltwater is usually used up in saltwater more quickly than other trace elements. While water changes can offset some of it, they can't offset enough unless they are done even more frequently than once a week. Iodine supplementation will allow you to strike a better balance, keeping water quality high and trace elements at healthy levels without wasting salt mix or effort.

I like the Kent Marine iodine supplement both because it already comes in a diluted solution which allows for greater accuracy in dosing compared to concentrates like Lugol's solution, and because I've had excellent results with it. Pretty much all of their marine and reef aquarium supplements are foolproof and easy to dose.

Never Forget They're Predators...

...and invertebrates are on the menu, no matter how expensive they are.

Although their temperament is usually mild in regard to other fish porcupine puffers are carnivores. Snails, crabs and hermit crabs, clams, barnacles, and shrimp of all kinds are all part of their natural diet.

Never forget their predatory nature because some saltwater aquarium inhabitants might be seen as food rather than tank mates. Even that fancy cleaner shrimp may look like a snack to your pufferfish. Mobile invertebrates are almost all on his menu of favorite foods. Corals, however, are a very individualized matter. Some individuals will eat or bite some or all types of coral while others will leave coral alone. Soft fleshy polyps of any sort are particularly tempting, even if not edible, and most balloonfish will take a little taste.

What Do Porcupine Puffers Eat?

They Love - and Need - Crunchy Invertebrates for Food

Porcupine puffers' teeth continue to grow their entire lives. Their teeth, sometimes referred to as beaks, must be ground down by the consumption of hard-shelled foods. If your pet's teeth become overgrown, he may become unable to eat and starve to death or require delicate dental surgery few veterinarians are willing or able to perform. If you want to keep your puffer's teeth ground down, be sure to feed him plenty of shell-on seafood, preferably at least a few times a week. While many porkies will crunch on ground coral just for fun you can't count on all of them to do it enough to keep their teeth trimmed.

Balloonfish are not piscivores. That means that, in nature, they don't eat fish. Do not feed fish, live or dead, to them. Feeding fish to pork puffers may cause something called fatty liver disease, a usually fatal ailment. Not only that but the nutrient balance found in fish is very different from that found in mollusks and crustaceans, their natural prey. Feeding fish, especially live feeder fish, to your porcupine puffer can also unnaturally accustom him to eating fish, making him a danger to future tank mates.

Carefully read the ingredients of any prepared fish foods you give your pet. Choose those with invertebrates such as shrimp, krill, squid, clams, or mussels listed as their first ingredient. Avoid all prepared fish foods with any type of grain or fish meal listed first in the ingredients.

If you buy frozen seafood for your porky read the packaging to make sure it has no added preservatives or ingredients. Fish are much more sensitive to odd chemicals than people are. If you buy mussels or clams from the seafood counter, be sure they are closed up tight which indicates they are alive. I prefer to let them sit in a bucket of used saltwater from a water change overnight to make sure they are alive and healthy before giving them to Porky.

Watch a Puffed Up Porcupine Puffer Deflate

This pufferfish parent was quick with his video camera and caught his young porky deflating. I think it's adorable! The little damsel fish popping into view is pretty cute, too.

Natural Defense Mechanisms

Will my balloonfish puff up?

Porcupine puffers have a dual natural defense mechanism. They are called puffers or balloonfish for a very good reason - they fill their bodies with water when frightened. This causes their bodies to look huge and their spines to stick out. Many a predator would change his mind when faced with a weird spiky ball instead of the fish he saw a moment ago or spit out a little morsel that suddenly sprouted sharp spines.

The fish in the picture, Porky, is only partly puffed. It is very hard to photograph him in a puffed up state as he comes swimming over begging for food as soon as he sees me, deflating along the way.

Don't try to scare your pet into puffing, it's very stressful to them when they puff in a panic. Given time, you'll eventually see him blown up like a balloon, an occurrence more frequent in very young specimens. It is thought that they puff occasionally to keep their skin flexible and to clean off built up debris that gets on their spikes which usually lay flat and mostly inside their skin.

Their other defense mechanism is having poisonous flesh. Porcupine puffers have a deadly toxin in their internal organs called tetrodotoxin. This makes it unlikely that a fish that eats one will ever eat another as dead things don't eat. Each moderate-sized balloonfish contains enough toxin to kill several human beings.

Oddly enough, the neuro-toxin found in their flesh is exactly what entices foolhardy gourmands to eat fugu, or sashimi made from puffer fish. In very tiny quantities, the toxin causes tingling and euphoria - and sometimes death.

So, whatever you do, don't eat your pet puffer!

You can expect to pay between $25 to $35 for a small porcupine puffer.

How Long Do Porcupine Fishes Live?

Diodon holocanthus lifespan

Their life-span in the wild is unknown but with proper care porcupine puffers can live at least 10 to 15 years in captivity. As these fish are relatively slow growing and take years to reach maximum size, and because of the large size of some specimens observed in the wild suggest it is likely that they have a similar maximum lifespan in the wild.

Your pet fish should outlast the average wild puffer, having the advantage of plentiful appropriate food, protection from predators, and treatment for parasites and diseases. The disadvantage your fish will have is a small living area, even in the largest of tanks but your careful upkeep and attention to water quality can offset that stress.

My porcupinefish is now at least thirteen years old and going strong. He's never had any health problems aside from a few minor wounds he suffered from getting attacked by Grape Tang (aka the Purple $@$&%$#), the purple tang he shares a tank with.

They Don't Mind Tank Mates

But NEVER put two of them together!

Like many species of saltwater fish, porcupine puffers should not be housed with others of their same species, which in the aquarium hobby are called con-specifics. If you put more than one in the same tank it will likely lead to the death of one or both of the fish.

They are usually pretty mild-mannered towards other types of fish. I'd suggest avoiding very tiny fish which, although porc puffers aren't piscivores, might be mistaken for food. I'd also suggest avoiding anglers and frogfish as tank mates. The little worm-like wiggling lure atop their heads would be too much for any carnivorous fish to resist.

Lionfish are often paired with porcupinefish but it's a combination I do not approve of. Lionfish have a tendency to stab any fish that frightens them with their venomous spines and pufferfish can seem intimidating due to their excessive curiosity.

Large species of fish make the best tank mates. Tangs, angels, eels, engineer gobies, foxfish, and squirrelfish all make good tank mates for the puffer. Medium sized fish that get along well with balloonfish include hawkfish, large clownfish, and wrasses.

Most invertebrates other than corals will be seen as food and some fleshy coral polyps will be as well.

My porcupine puffer lives with a Regal Tang and a Purple Tang (pictured) in a tank with a frogspawn coral, encrusting montipora, several fungia coral, a favia coral, zoanthids, and an elegance coral.

They Have Cute Personalities, Too!

Porcupine puffers are one of the most personable types of saltwater fish. They quickly learn to come to those who feed them. They can also learn that doing a little dance or spitting water above the surface can get your attention and may earn treats. However, don't give in to their begging too often as overfeeding can cause serious health problems.

I ate fugu in Japan at a specialty fugu renutarast in Osaka -- but also have eaten bits of fugu in Hong Kong. At no time did I get that tingly sensation that I was expecting -- and hoping -- to have... Ah well! But, OTOH, I guess I should thank my lucky stars I didn't get sick from eating bits of the fish as well! :D

That's a great idea. I used to feed mine with a turkey baster. When he gets a bit bigger you will want to become fast with it and get it out quickly. My Porky eventually bit the end off getting overexcited at feeding time but he was much bigger than your little guy is now. It was OK though because he just spat the plastic back out in little bits. I do all the fun leading him with the food outside the glass sides and drop it into his open mouth from the top when he comes up to beg now. It's just as enjoyable and everybody gets to keep all their fingers.

You are going to enjoy your little guy so much. Porcupine puffers say cute forever and develop more complex and entertaining behaviors as they get older.

Christine brooks 24 months ago

Thank you for your advice. I will try a turkey baster instead if you think that's ok because he seems to know when i am feeding him and waits for my finger to go in the water with food on

It is unwise. His teeth will soon be able to crush clams and the wee bones in your fingers aren't much more substantial. Your pet is a wild animal and he may well bite you eventually. While they can learn some things, they just aren't smart enough to learn to never bite you.

Christine brooks 24 months ago

I have a baby porcupine puffer. He id approximately 2 inches long and he likes being hand fed but does tend to bite my finger. Is this unwise as he is obviously going to get bigger as are his teeth or will he learn to be more gentle. He hasn't broken skin yet.

@spuddy123: About all you can do for a stressed out or sick fish that doesn't have any infections is to give him supportive treatment like immaculate water quality, fresh food, and steady, appropriate water temperatures. Keep his tank water extremely clean with no detectible nitrates, nitrites, or ammonia. Keep his PH around 8. Keep his water temperature between 75 and 80 degrees. Feed him thawed, invertebrate-based frozen fish food or things like chopped up fresh shrimp, mussels, clams, or crayfish until his appetite comes back.Good luck with your puffer.

@agiffey: They crunch the shell into shards and somehow manage to spit out all of the inedible fragments. They chomp as much meat as they can reach out of a half shell then start crunching up the shell to get to the last of it. I'd like to know what exactly goes on in their mouths because they can pick up tiny pieces of food with a mouthful of substrate and only spit out substrate through their gill openings! The really strange thing is to watch Porky eat a small crayfish. He sucks in part, chomping, spits it back just a little, then sucks in the whole thing and spits out all the parts he doesn't want through his gill slits. I have no idea how he sorts stuff inside like that.

agiffey 2 years ago

Curious how the puffers actually eat the small clams. Even clams on the half shell. Do they just crack them open with their teeth and eat the whole thing? Or just try to scrape the meat from the shell?

@bonesindecay: You could have it ready right away if you use water from your cycled 100 gallon and attach the Eheim right to the quarantine tank. Hypo-salinity needs to be phased in slowly. You start at a normal salinity and slowly decrease it briefly to around 1.010. I'll have to hunt up the instructions for that. I've had my fish so long haven't had to quarantine anything but macroalgae for probably ten years.I'd suggest you treat both the display tank and the quarantine tank with a reef-safe ich-treatment. You'll really enjoy the chromis because they are such neat schoolers. In time, you can train them to come to you for food and they all come swimming to you at once. They also don't tend to get nasty or annoying like damsels.

bonesindecay 2 years ago

@Kylyssa: Thanks for the reply. I have a spare 10 gallon tank and a small canister filter I could use for quarantine. How long do you recommend I cycle the quarantine tank before it's safe to put fish in the quarantine tank? Also how long do you recommend doing the hypo-salinity & quarantine before adding the tang and any fish to the main tank? Isn't it more risky putting these fish in a smaller tank? They can still get stressed out because it's too small right?. I do plan on getting a baby Porky and a baby tang. I was thinking I should probably exchange the 4 damsels in my tank right now for a couple chromas since you told me they can be butt heads to the blue tang. Thanks again for your advice.

@bonesindecay: Yellow tangs are easier to take care at first of but tend to be a bit more aggressive than blue ones. By aggressive I mean they tend to bully other fish and nip fins even when it might be suicidal and the one I had was a terror on corals and decorative shrimps as well. I gave her away after she killed a big, beautiful foxface fresh out of quarantine, cut his abdomen right open. My experience with all the Zebrasoma tangs is that they can be nippy little jerks. My purple is nicer than the yellow was but he still has the name Purple (bleep) because he picks on Porky and the Hippo. Hippo tangs are harder to care for at first and are susceptible to ich but you can use hypo-salinity in the quarantine tank and nip it in the bud before adding it to your display tank. Everyone I know who has a blue agrees that once you get your blue past its first six months in captivity it's a sturdy critter. Mine's been crazy healthy for the last ten years, even surviving a really big bite out of her cheek from the Purple (bleep) tang about four years ago. Yellows are only slightly less susceptible to ich and seem slightly more susceptible to what they call black ich. The bottom line is that all tangs are ich magnets, there's only different levels of degree. Blue tangs are really calm and pretty smart once they're a year or so old, even feeding off the surface and taking tidbits from your hand in time. In my experience, blues do better at adapting to a wide variety of foods and seem to eat heartily quite quickly and yellows sometimes don't.One weird thing about adding a blue tang is this - if you have a yellow and blue damsel, the damsel may get really aggressive with the blue tang. The yellow and blue damsels don't seem to know that the blue tangs aren't conspecifics. It might not seem like a damsel can do much to a blue tang but they can harry and annoy the poor thing until it stops eating or gets infected from the nips. So I wouldn't do a blue tang with a yellow/blue damsel.You'd probably do better with a tang than a wrasse, especially with the clown in there. I'd keep the Eheim going permanently. You can always use it to stick a sponge filter into mature for you to use in a quarantine or hospital tank and a little extra filtration is never a bad thing even if you don't. It looks like your email went straight to the Spam filter. Yahoo mail can be a pain like that. Anyway, I think you've got a nice looking set-up going and it's going to be awesome once everybody gets settled in.

Hello Kylyssa,Hope all is well with you.My 100 gallon has been going for almost a month. I have my refuge set up in my 15 gallon tank. I have it set up by the siphon method beside the main tank The timing of the siphon and my return pump has been stable. I recently purchased a protein skimmer, the Eshopps PSK 100H. The skimmer seems to be working really well. I have 6 small damsels in the tank right now for about 5 days now and they are doing well. I do have a couple more questions for you though.In about 1 to 2 months I plan on getting the Porky Puffer as well as an engineer goby or a large gold stripe maroon clownfish. But I am debating over getting a blue hippo tang or a yellow tang. I have read that most tangs are susceptible to ich and the blue tang is one of the worse. Most say the yellow tang is easier to take care of. What are your thoughts about the blue vs the yellow? Also I was considering getting a Lunar Wrasse. But I'm skeptical because I read that they are supper aggressive and I wouldn't want the wrasse freaking out and nipping at the puffer's eyes or other fish... etc. What do you think about me getting a wrasse? Or should I just keep it to having a Puffer, Yellow tang, large maroon clownfish, and damsels in my tank?I am still running my Eheim 2217 canister filter. Do you think I should still run the filter or stop? My tank is filled with about 1/2 live rock, 1/2 fake rock and live sand. I only have a few sponges in my refuge, so If I take away the canister filter I'm not sure if it will be a good idea. I have some photos of my set up that I emailed you.Thank you for your time.Jared

@bonesindecay: It will certainly help. I highly recommend cheatomorpha macro-algae for your refugium. It sucks out nitrates like crazy and you can feed the extra to your tang when it outgrows the refugium. It also doesn't go "sexual" and have die-off like the caulerpas do.

@bonesindecay: I think that's an awful lot of bio-load for that size of a tank without some extra water volume and/or filtration. Engineer gobies get to be a foot long or even a bit more sometimes. The blue/yellow damsels stay tiny so multiples of them would likely be fine but I'd recommend only one three-stripe damsel (they get bigger and may get aggressive with each other) if you go that way. Any type of damsel will be fine with the puffer as he's likely going to be a lot less aggressive than you may think. They eat mostly invertebrates in nature and won't bother with even small fish unless confused or very hungry. I actually used to use my tank with Porky and the engineer as a tank to put injured fish into to recover because both were very mild fish. Porky takes food from the mouths of fish whose faces he could bite off if he weren't careful. Some damsels may pick at the engineer goby. Engineer gobies are mild mannered fish when it comes to fish too big to fit in their mouths. Engineer gobies tend to hide from any confrontation but they can become friendly enough to hand feed. A ten gallon change per week is a very small change for a heavily occupied 100 gallon aquarium. Such small water changes can be OK if you have a vegetable filter such as a refugium full of macro-algae but I wouldn't recommend it if you just have the tank. The EHEIM 2217 is a good filter for a moderately stocked 100 gallon tank. Even though Eheim claims it's good for much larger tanks, if you compare the volume, amount of media space, and the liters-per-hour of turnover with other brands such as Fluval and see what tank sizes they are rated for, you'll see the Eheim is rated with a very different standard. The Eheim 2217 is a great filter and would be perfect for a moderately stocked 100 gallon, though.

bonesindecay 2 years ago

@Kylyssa: Thank you for the info. My name is Jared. I have the 100 gallon with water live rock and sand in it now. In a couple months I was thinking of getting the Octopus HOB BH 2000 protein skimmer ( especially when the porky is in the tank). I am using a EHEIM 2217 canister filter. I can't afford a sump or refugium set up right now. Maybe in the future. I will try to keep the tank clean as possible and change 10 gallons a week.I think I will start out with some damsels. Then get the puffer, a blue hippo tang and a couple engineer gobies. What do you think? Also you recommended me to get a couple 3 striped damsels in the email you sent me. Are those really aggressive? Wouldn't it be better to get some blue/yellow damsels? If the puffer decided to eat them it wouldn't bother me much.Thank you for your time.Jared

Kylyssa 2 years ago from Overlooking a meadow near Grand Rapids, Michigan, USA Author

@bonesindecay: If you haven't bought the tank yet, you may wish to consider something a little larger. If you already have the tank, I'd suggest a very large refugium or sump under the tank to add water volume. An over-powered protein skimmer would be in order, too. You can put it in the extra-large sump or refugium. Any damsels or chromis that survive will stay small and won't add too much to the tank's bio-load but both porcupine puffers and Picasso triggers get big and hefty. It still seems like an awfully large bio-load for a 100 gallon. Think about how long and how thick a foot-long fish is. Also keep in mind the trigger will grow much faster than the porcupine puffer so you'll probably want to start out with a porcupine puffer much larger than the trigger. That should also help from a cost standpoint as large porcupine puffers are relatively inexpensive and small Picasso triggers are much cheaper than large ones.

bonesindecay 2 years ago

Hello, I'm new here. First off I would like to say that Kylyssa wrote a very good article on the porcupine puffer. The porcupine puffer is an awesome fish! Unfortunately the porky puffer would not do well in my 30 gallon. I have had a 30 gallon nano cube salt water tank for over 3 years with a maroon clown fish, a damsel and the tank is good. I am currently upgrading to a 100 gallon tank because I have fell in love with the porcupine puffer. I have done a lot of research and had mixed reviews on the porcupine purffer. My question is will it be able to handle the porky be able to handle my 100 gallon tank even when it is full grown with the fish I plan to add to my add to my aquarium? I was thinking of having about 5 blue/yellow damsels, 5 chromas, a Picaso Trigger and of course the PUFFER. (Im not worried about the puffer or trigger eating the damsles and chromas) Trust me I will make sure the tank is clean. If anyone can reach out and give me any advice that would make my day. Thank you

@Kylyssa: Thanks, Kylyssa! Floyd, our is at about 6"-7" now and we are currently in the process of getting a much larger tank. The p.puffers I've seen locally appear to be about 3-4". We're not rushing out to get him as we still need to prepare a much larger tank. Again, thanks for the advice!

Kylyssa 4 years ago from Overlooking a meadow near Grand Rapids, Michigan, USA Author

@mdarbyvancouver: As with any combination of fish in a tank together there are no absolute guarantees they will get along. However, as long as the porcupine puffer is substantially bigger (when not puffed) than the grouper's mouth they stand a good chance of getting along. One concern to keep in mind is that the grouper, if it hasn't reached its adult size of close to two feet long, will grow very fast in comparison to the porky puffer (my porcupine puffer continues to grow after having him eight years and he's only just reached 8" long) so you'll want to start with a porcupine puffer already too big to be swallowed by a full-grown panther grouper. Porcupine puffers are actually pretty mild-mannered and slow-moving so you may have to hand feed him (it's fun anyway) or risk overfeeding your grouper to get enough food into your porky. Good luck!

WoW! Great info and great advice! One question: do porky puffers and panther groupers get along? Just askin' as we have a panther grouper(also very playful and very social) and want to bring in a p.puffer. Thank you!

This is excellent advice for anyone considering a porcupine puffer. It's easy to see why people would rush to buy one, they look so cute and we are all fascinated with the puffing trick too, but they are living beings with their own particular requirements and it is important to stop and consider first whether you can give a puffer the care it needs.

This is a really well put together lens about porcupine puffers! There's a lot of great info :) I'm glad you mentioned that people should never scare their puffers just so they will puff up - I can't tell you how many times I've had to explain to guests that I will not make our puffers puff just so they can see it.

Porcupine Puffers look like very funky fish! An excellent and informative lens blessed by this Squid Angel as part of the "Back To School Bus Trip"!

Your porcupine puffer looks like Gollum in the last picture! Maybe you can make him famous:) I have a fish tank at home, but not saltwater. I would certainly consider buying a puffer fish if I ever make the move to salt water. Blessed

These fish are so unique. Right now I have a small fresh water tank but maybe someday.....

I believe I saw a porcupine puffer when I was in hospital once. I always wondered what it was. It certainly liked to come right up against the glass when it thought I was looking at it. Thanks for solving that mystery! They're pretty cute fish and thanks for all the tips you've shared about keeping them!

Nice lens and thought provoking for carers of them. It is very topical and well written.

Never heard of these marine hedgehogs, they look really cool and I find the facts you told very entertaining. About them being intelligent and some people eating them just like the fugu fish. Great job! ***** and favorited

Funny I am reading this - we had a puffer fish in our tank that was aggressive and literally took a bite out of one of the other fish - of course that fish died. My husband watched the whole thing take place. So this week my husband found it a new home with a fish tore employee and may all the other fish in my tank be happy while their fins all grow back.

I had never heard of this type of fish before.
