Betta fish suffers from a number of health conditions, but the good news to the keepers of this type of fish is that these health problems can be prevented and also treated. If the infections occur in the aquarium, they can be easily identified and treated effectively.

This article covers all the common diseases and illnesses of betta fish, their prevention, diagnosis and treatment. So if you keep the Siamese fighting fish at home, read on to learn how you can keep your aquatic pet healthy.

Betta fish diseases and illnesses are categorized into fungal, parasitic and bacterial. Most fungal infections result from previous health conditions. Parasitic ailments are the most contagious and can be introduced into the aquarium by new fish. The most common causes of bacterial sicknesses include poor quality water and inappropriate fish handling methods.

The Common Diseases of Betta Fish, in Brief

Fin and Tail Rot
Columnaris
Hemorrhagic
Dropsy
Pop Eye
Eyecloud
Mouth Fungus
Furunculosis
Fish Fungus
Velvet
Ich
Anchor Worms
Hole in the Head
Swim Bladder Disorder
Betta Tumors

1. Fin and Tail Rot

As the name suggests, this disease affects the fins and tail of betta. It can be caused by bacteria or fungi. The fins and tail appear to melt away as a result of rotting.

It can be prevented by keeping the aquarium or living conditions of the fish clean.

Fin and Tail Rot can be treated by medications containing antibiotics, such as trimethoprim, erythromycin and sulfadimidine.

If it is effectively treated, the fatality is medium.

If you have had Fin and Tail Rot affecting your fish, you may have tried medications such as Tetracycline, Jungle Fungus Eliminator (JFE), Maracyn or Melafix. But the truth of the matter is that these medications are not quite effective in treating this infection, and some even kill your fish.

I have had little success with JFE and the other medications showed no success - they even worsened the condition. According to my own experience, the most effective medication for Fin and Tail Rot is Waterlife-Myxazin manufactured by a reputable company.

The medication is itself a 5-day treatment, and it comes with clear instructions on how to use it. The most amazing thing about this treatment is that it starts to give positive results from day one! According to the manufacturer, it can also deal with pop eye, body rot, raised veins, ulcers, 'redness', cloudy eyes and other health conditions.

If you have the Fin and Tail Rot disease or the related infections in your aquarium, I would encourage you to go for this medication. I have been using it since I discovered it in 2010 and I have had no disappointments with it.

2. Columnaris

This is a bacterial disease that causes the fins to rag and fray. It also causes skin ulcers or lesions, white spots on the mouth, cottony growth on the mouth, scales and fins, and gills discoloration. The fish can have breathing difficulties as a result of the gill infection.

The sickness can be prevented by treating open wounds and fungal infections. It can also be prevented by avoiding factors, such as limited oxygen, water hardness and overcrowding in the aquarium.

Columnaris can be treated by Oxytetracycline and antibiotics containing Sulfa 4 TMP, TMP Sulfa and triple sulfa.

If the infected fish is not treated, it can die in less than 72 hours.

3. Hemorrhagic

Commonly known as Redmouth, Hemorrhagic causes serious bleeding inside the mouth and eyes of the fish.

The disease can be prevented by disinfecting the aquarium to kill Yersinia Ruckeri, which is the bacteria causing the illness.

The treatment of Hemorrhagic is possible with antibiotics such as ampicillin.

The infection is treatable, which means that the fatality is low.

4. Dropsy

This is a deadly ailment that affects the kidneys. The infected fish can have swollen abdomen as a result of accumulation of internal fluid.

Some more symptoms include; outward-sticking scales and sunken eyes.

The bacterial infection can be prevented by keeping the aquarium clean. It can also be prevented by feeding fish with vitamins-rich foods.

There is no known cure for Dropsy but medications, such as Betta Revive, can help with the condition.

Most fish that suffer from Dropsy do not survive.

5. Pop Eye

This disorder causes swelling on one or both eyes. The swelling can be a tumor or viral infection.

Pop Eye is usually a symptom of a disease and can be avoided by preventing infections in the aquarium.

Antibiotics such as Tetracycline can cure the ailment.

Most fish that suffer from Pop Eye survives at the end.

6. Eyecloud

Commonly known as Cloudy cornea, this disease causes white films on the eyes.

It can be prevented by improving the quality of water. A water conditioner is needed to make the water safer for the aquatic animal.

Eyecloud can be treated by antibiotics such as Metafix and Fungus Clear.

The bacterial sickness is not fatal but can impair vision.

7. Mouth Fungus

This is actually a bacterial disease, and it causes white lines and clumps around the lips and mouth of the fish.

It can be avoided by keeping the water clean.

Amoxicillin as an antibiotic can cure Mouth Fungus.

The infected fish cannot survive if the illness is not treated early enough.

8. Furunculosis

The symptoms of Furunculosis include skin ulcers and open red sores.

Improving water quality can effectively prevent the disease.

Fungus Clear as an antibiotic can treat this bacterial ailment.

Furunculosis can kill fish that doesn’t receive treatment in time.

9. Fish Fungus

This is a fungal disease that originates from previous infections. The affected betta usually has cotton-like growths or slime (mucus) on the skin.

It can be prevented by avoiding primary infections and injuries and keeping the aquarium clean.

Antibiotics such as Methylene Blue and Fungus Clear can cure Fish Fungus. It can also be treated effectively by the Bettafix Remedy mentioned below.

The sickness can become fatal if it is not treated early enough.

10. Velvet

Betta infected with Velvet appears to have a rusty skin.

The parasitic disease can be prevented by improving the quality of water and ensuring the living conditions are stress-free. Water conditioners are some of the best substances to improve the living conditions.

It is highly contagious but it can be treated fully by Bettafix Remedy. Manufactured by Aquarium Pharmaceuticals, this medication consists of curing components such as sodium chloride, copper sulfate, acriflavin, formalin, sulfa 4 TMP, methylene blue and malachite green.

With all these healing components, this remedy can also be used to treat all the other diseases, illnesses, sickness and disorders listed on this article. I have been keeping bettas for almost 15 years, and I have seen this medication heal my aquatic pets. I recommend that you use it to prevent, control and treat many ill-health conditions.

If Velvet is not treated early enough, the infected fish dies in a matter of days.

11. Ich

Also known as White Spot, Ich or Ick is a parasitic disease that causes white dots or spots on the skin of betta fish.

It can be prevented by changing the water regularly.

The sickness can be treated by Fish-zole, Malachite Green or salt baths.

It is very easy to deal with the illness if treatment starts early.

12. Anchor Worms

This is a parasitic disease that attacks the tail or fins. The affected parts appear red and swollen and have protruding worms and threads of slime.

It can be prevented by treating any newly infected fish and keeping the water clean.

Some antibiotics such as Methylene Blue and Parasite Clear can cure the disease.

The ailment can become fatal if it is not treated early enough.

13. Hole in the Head

Betta infected with Hole in the Head have an abrasion on the head that looks like a pinhole.

The parasitic infection can be prevented by cleaning water off carbon.

Parasite Clear is an antibiotic that can cure the disease.

The infected fish usually dies after a few days if it is not treated early enough.

14. Swim Bladder Disorder

Also known as flipover, this disorder forces the fish to float at the surface of the water. The affected fish swims sideways or upside-down and can also lie at the bottom of tank. It is caused by constipation, poor water conditions, parasite or bacterial infections and enlarged organs.

It can be controlled by maintaining a high quality water, avoiding overstocking and feeding the fish with the right amount of fresh and fiber-rich foods.

When it comes to the treatment, the swim bladder disorder can be stopped by raising the water temperature, letting the fish fast for some days and then feeding them with cooked peas.

15. Betta Tumors

Betta tumors are usually cancer lumps or minor bumps/cysts under the skin of the fish. They mainly affect the reproductive organs, gills, tail and abdomen, and are caused by genetic mutations and viral infections.

The tumors can be controlled by feeding the fish with healthy foods, maintaining a clean tank, treating other infections and keeping carcinogenic substances away from the tank.

As far as treatment is concerned, the malignant tumors can be hard to cure, but some simple surgical operations can help. The benign tumors and cysts can be treated in a number of ways depending on the cause the lump or bump.

Questions & Answers

Question:
My new Betta fish, that I got from Walmart (so you know it was in horrible conditions before I got it) is now gasping at the top of the water; he flares up anytime that anyone comes around him, he's not swimming like a normal Betta fish does either. He's my baby brother's fish, and he would be devastated if it were to die. What can I do to treat him?
Answer:
It looks like you have fed him a lot, and as a result, has developed the swim bladder condition. See how to deal with the condition from the article. He could also be under stress because of the new conditions, so you can also wait to see if he'll get better.

Question:
Can you help me? My fish has been sick for about a month. I've tried everything. He will have fuzz on his back that looks like Columnaris. It'll go away a little before it returns looking like a dandelion! I feel terrible that I can't help him...the fuzz looks like that in the Columnaris picture, but it could also be fungus. I've treated him with Lamenting and Metronidazole, and then fungus cure separately. I have also tried Methylene blue. Please tell me what I can do.
Answer:
The problem could be the water and other elements in the tank. You need to start charging water regularly, and you can begin by performing a 100% water change.

Ammonia build-up has been studied to cause all sorts of ailments in fish. You need to ensure that the amount of ammonia, nitrites, and nitrates is below 40 ppm. To lower these compounds, you can do the following.
- Change water regularly.
- Scoop out unnecessary organic matter like food remains, rotting plants and dead fish.
- Vacuum/clean the gravel.
- Unclog the filter.
- Cut down on feeding.
- Avoid overstocking.
- Introduce healthy bacteria.
- Lower pH.
- Increase aeration.
- Use ammonia neutralizing/removing pellets/drops.

When performing a 100% water change, let the tank dry in the sun and soak its accessories in hot water. If you have plants, get them outside to vaporize any water on them. When adding fresh water, include some aquarium salt or conditioner, and ensure the water temperature remains between 26-27 degrees C.

After changing the water, cleaning the tank and obtaining the right water parameters, you can continue with the fungal medication.

There could be some issues with your water. You need to get water from a trusted source - your source may be offering water with harmful substances, or you could be adding them without knowing. You also need to change it regularly and maintain the right parameters - ammonia, nitrates, nitrites, pH, etc. See all parameters in the comment section of this article.

Question:
My betta has lost her scales on her head and is bloated. I have tried fasting her and have decreased her feeding. No results have shown, I moved her from my male betta and given her more hiding places. She has no lights in her tank and is continuously losing more scales. What is happening to my betta?
Answer:
After the changes you have done, you can give her some time to see if there are some improvements. But you need to optimize water parameters - ammonia, nitrites, pH, etc. She could be having a reaction from these parameters. See all parameters in the comment section of the article.

Answer:
If it's a hard lump, it could be cancerous which is difficult to cure. Otherwise, it is a fungal or bacterial infection which can be cured with medications such as Maxyazin and Bettafix Remedy mentioned in the article.
Helpful
Question:
My beta fish is lethargic, not eating as much, losing his color and staying calm between artificial plants, what could be wrong?

Question:
My red betta has white spots all over, and her jaw is turning white. How frequently should I change the water? What temperature should I maintain? Also, how do I condition the water before I change it?

My beta has one gill that is sticking out. We have used a Melaleuca antibacterial for a week, which has not helped. Do you have any idea what this is?

My Betta has some white cotton-like fluff hanging from his fins. I’m not sure what exactly it is, but my best guess is some kind of fungus. He came with it and we have been fighting it for several months, but we can’t seem to curb it entirely. We have been giving him Jungle Fungus and putting a small amount of aquarium salt in with water changes but the mystery fungus just persists! It doesn’t seem to alter his energy level as he still zooms around with as much energy as ever. Any insight into what might be going on and what we permanently knock this fungus out for good?

@Sandra I think you are doing everything right. Most of the symptoms you see are just out of the pain of the injury. Some times fish can go for days without food, so this is not a big issue.
May be you can change the water regularly to keep harmful bacteria away, and try to disinfect the wound. You can also try keeping him off the sharp/rough objects

Hello, I have a veiltail betta fish named Scottie and he is not doing very well. He was the only fish in a 5 gallon tank with a heater, a filter, some artificial plants and a hiding spot. He was doing fine until Dec. 9. Scottie doesn't like to come out of his hiding spot after dark, but my sister wanted to see him, so she shook his tank and spooked him.
That was on Dec. 9, and i only found out that she did that 2 days later because someone told me. The edges of the inside of his hiding spot were sharp, so when he got spooked, he cut himself badly. After that, he was lethargic and hasn't eaten since(i feed him betta pellets by the way). It's been 9 days so far and he still hasn't eaten. I recently moved him into a smaller tank so he could reach the surface easier to get air. Now he is still lethargic and stays at the bottom of the tank, but at random times, he darts around crazily. His injuries seem to have cleared up a little, but every time he swims up for air, he just sinks back to the bottom. He seems to be breathing heavy sometimes, and he is still not eating.
Sometimes he swims a little bit at the bottom, but then he stops and lays against the side of the tank or the gravel, or on one of the Luffy betta balls in his tank. This was originally my sister's fish, but she wasn't taking care of him. His water was filthy and he was in a bowl. No heater, and a bubble over his eye. So i've had him for about a year now, gradually learning how to properly care for a betta fish, because I didn't really know either. I just felt bad for Scottie. He was doing good until she came over and scared him last week. She didn't buy any necessary items for Scottie except Start Right water treater and pellets, so I bought him a heater and filter and larger tank and decorations. I plan to buy Aquarium Salt, Melafix Remedy, and some live plants instead of fake ones(so he won't hurt himself anymore, IF he makes it through this) this Wednesday to see if that helps Scottie. I don't know what else to do. Please help.

I lived in Taiwan and then American and I followed all the procedures that are needed for keeping bettas. I did 20% water changes I use a little bit of aquarium salt, water dechlorinator I have a tank that's at least 3.5 gallons. I have a life plan to place for them to hide. I have a low flow filter for one of my tanks and the other two I need to switch over because maybe the flow is too strong but only on one of them. Now I have pellets in Taiwan they don't have blood worms and flea eggs. and absolutely no products from Omega one.
But in the last three months I've had for betta's died and 6 Guppies...... what killed the betta's most likely fin rot but my last betta it had a filter but he didn't die from fin rot I don't know what he died from he just lost his color and died.
now living in Taiwan they say all the opposite. They don't need a filter because we're supposed to do 20% water change. they need a heater but they need me no more than half a gallon tank.
I really don't know how to keep my betta's alive. I just bought a beautiful Orange County jail for the equivalent of 5 US dollars so I'm going to keep him in a half gallon tank what the life plant and heater and see how that works. I put in the dechlorinator and a little bit of aquarium salt with aloe Vera. Plus you'll have a light so the plant can get with it needs and I'll put one drop of plant food in. I really don't know what to do. I've got a red veiltail he seems to be doing fine now the tip of his tail turned gray a little bit I don't know if he was feeling stressed because maybe the filter was too strong. but my little baby she's in like the equivalent of a 1 gallon glass aquarium she's got a low flow filter and heater. I was afraid if I got her something bigger it would kill her. ..... but the small pet store that I went to they've been raising fish for 20 years and all their betta's look really good it's sort of like Russian Roulette.

Before doing current research on bettas I went out to buy two female bettas for my male betta as I had learned along long long time ago that it was the only dynamic they would do well in. So as I was slowly trying to get them accustomed to one another (before my current research) I was having them in the same tank. Obviously it didn't work out so that's when I found out that this was not an ideal social setup so I separated them. I don't think my females were sick when I bought them but now all three of them seem to have similar signs of illness that I noticed only after I started feeding them bloodworms. They are all acting fine with no change to their behavior however they have physical marks on them that were not there previously. They all have what seems to look like two slanted very pigmented red scars near their gills on both sides of their bodies. There is a more noticeable underlying redness to their faces, no swelling whatsoever. So I don't know if this is an illness or not, or if it's due to their tank, to the newly introduced bloodworms, or something else. Seeing the stuff on the list gives me a couple options of what it can be but they don't show any other signs of those illnesses. It's just the redness that is the only factor in those illnesses. So I am still lost as to what it could be if anything. Any help would be so greatly appreciated, thank u.

As answered in the questions section, this is highly likely to be an early sign of velvet. You can try changing water more often and keep the water parameters right. See the parameters in the comment section of the article. As for the treatment, follow the Bettafix Remedy link in the article to get the medication.

My white betta (unsure of the gender) has red on the top of their head, almost like a rash, I've had it for about..3-5 months i think. It's also a bit unresponsive sometimes when i feed it, I use Wardley betta food, they are small pellets.Its been there for a few weeks and they're also a bit pink almost, I'm really concerned. Any clue what any of this could be?

Well, if he looks pretty normal - no signs of sickness, then it is highly likely to be nipping.
On the other issue, white spots are usually fungal. You can follow the link in the article to get a Bettafix Remedy.

For the past 3 days my approximately 6 month (we've had him for 3) male veiltail betta's caudal fin has started to look very ragged, to the point of becoming stringy from chunks missing. folks who see the photo say he is nipping (wish i could show photo). How do you differentiate nipping from fin rot? Columnaris? If he is nipping, what do we do? 3 gallon tank. Water parameters are all good. Temp 78 degrees. Moss balls. Artificial plants. 1 Nerite snail. Always keep a couple small Indian Almond leaves, low dose of aquarium salt.
Also just noticed small white spot on his left gill cover, size of single scale or so. Definitely new.

If she is acting normal, it is highly likely to be a problem with the water. You can try changing the water regularly and maintaining the right water parameters. See the parameters in the answers above.

Hello,
My sweet female betta fish has 3 hard(looking), white bumps on her body. Biggest one on the top of her fin. She is acting perfectly normal, eating well , and the rest of her looks great. Good color, fins and tail look good.
What could these hard looking, white bumped be? And how to treat?
Thank you !!

If it's a large area, it's highly likely to be a velvet developing. Get the Bettafix Remedy mentioned in the article to control the infection!

You can try keeping the water parameters optimum. Keep the right levels of pH, ammonia, nitrites, organic matter, etc. See the parameters in the comments above, and try to give him some time to see if there are any positive changes.

Hi,
My betta fish has fins rot. I have tried everything: change its water frequently. Used bettafix. The stopped it since I read it does not work. I also used JFC tablets, but I don’t see any improvement in the fins. He eats well and swins and rest normally, but I don’t see its fins recovering. What else can I do? Please help

Like I have answered in the Q&A section, if she is not showing any signs of sickness, it is highly likely to be a developing bodymark. So don't worry, but keep a keen eye on her to act immediate in case it's not a mark.

My new betta I got had a small red spot on top of her head. I have her in quarantine before I add her to my sorority. I can’t tell if the spot is still methgoing by that needs to be treated. I can’t tell if it’s just a scale though. Should I treat her and what for?

If she was fine hours before, then it is likely that she was bruised by a sharp object in the water. You can disinfect the wound and keep the water extremely clean.

It is highly likely to be swim bladder or bloat. See the remedies for swim bladder in the answers above. As for bloat, just cut down on the amount of food you're giving him, but let the food feature some peeled pea.

PLease HELP! My Betta is having issues and I’m very concerned for him, I’ve had him for 2years now and a few days ago I noticed him laying at the bottom of the tank, the next day he was still there and barley moving around. My boyfriend bought some medicine for him because he looks like he has tail rot but he might have another problem he looks really bloated and lays side ways and sometimes vertical and doesn’t look like he’s breathing. I’ll shine a light at him and he’ll swim up the the top get air and fall back down slow vertical again :( I don’t know what to do now.. I have him being treated in a little fish bowl and now using water conditioner.. he was in a 5 gallon tank when he got sick. What does this mean when he’s vertical could he have kidney disease or something??!? Pls help .. thanks in advance!!!
