How to Grow Sea Monkeys

Updated on March 19, 2018

For my 5 year old sons birthday this year, I decided to get him some sea-monkeys. I had the pleasure of owning sea monkeys when I was a kid and I remember being very excited about them! I was happy to have them and they actually did very well until one day the little aquarium fell to the floor, along with everything in it. That was a very sad day for me but now I have some more! Ahem, I mean, my son has sea-monkeys and I was more than happy to help him get them started.

These are better than the ones we had back in the day. These new and improved "hybrids" grow larger and are guaranteed to live up to 2 years. There is also lots of additional accessories and supplies to purchase for those with a sea-monkey obsession. You can get medicine, banana treats, growth stimulator, mating powder and lots more! You can even get a cool light up aquarium for them now.

Many places have sea monkey kits for purchase. I got this one at Wal-Mart in the toy section. The kit does come with instructions but I decided to go ahead and share them again here. You never know when someone might need instructions on how to grow these amazing live sea monkeys!

What You Need:

You will need the sea monkey kit which is the actual tank and inside will be a small measuring spoon and three packets:

  • Packet 1 -Water Purifier
  • Packet 2- Instant Live Eggs
  • Packet 3- Growth Food

In addition to the kit, you will need some distilled drinking water to put into the tank and a plastic spoon for mixing the water in your tank.


**Important** Don't put tap water in the tank. It's bad news for the monkeys. If you don't have any distilled drinking water, just boil some water and let it sit and cool and use that. That's the same as distilled water.

STEP 1

Take your empty tank and pour in the distilled water up to the "full" line that is on the side of the tank. Take packet #1, which is labeled Water Purifier, open it and pour all of it into the tank. Then take a clean plastic spoon and mix that around in the tank for about one minute. Put the lid on it and let it sit for a FULL 24 hours. Also contained in packet #1 is a secret hatching catalyst!

***We didn't have a plastic spoon to mix ours so we used a clean straw. I don't think it matters as long as whatever you use is clean and everything gets mixed up but they do recommend using a plastic spoon.

STEP 2

Now that 24 hours have passed, open packet #2 which is the Instant Live Eggs and pour the entire contents into the tank. After you empty the packet, stir briefly. Then you can hold your aquarium up to the sunlight or a strong light and you should see something that looks like wiggling little dots. Those are your baby sea monkeys...some will start hatching immediately!

Though you should see some hatch instantly, hatching time vary depending on the temperature of the water and also the thickness of the egg shells around the sea monkeys. Thinner shells hatch quicker than thicker shells and if the water is cold, it will take them longer to hatch. Read the helpful hints that come with the kit, it explains all the different things you will want to know.

Now that you have added the instant live eggs, put the lid back on enjoy seeing your sea monkeys grow. You don't have to do anything else for another 5 days.

STEP 3

Now that 5 days have passed since you added the live eggs in packet #2, it's time to start feeding your sea monkeys and their food is what is in packet #3. Take the double ended measuring spoon that came with the kit. You will notice it has a small measuring spoon on one end and a larger one on the other. Use the smaller measuring scoop to measure out the food for your sea monkeys. On the package it says to feed them ***one level small scoop of food from packet #3 and put that into the tank. After this, according to my research online, it's best to feed them every 5 to 7 days.

***Important*** On the back of package #3 (food package) it says to feed them every two days but after researching online, I noticed that most people feed their sea monkeys every 5 to 7 days. Also on the sea monkey website it says give only half a small scoop to the sea monkeys each feeding. I don't know why the package says 1 level small scoop and the website says half a small scoop but I've decided to just give our sea monkeys half a small scoop every week. It seems it's better to underfeed than over feed them and ours seem to be doing fine with it. Of course, it's up to you about how much you want to feed your own, I just wanted to point out the discrepancies that I found and what seems to be working best for us so far.

Continued Care for Sea Monkeys

Sometimes the water may get cloudy in the tank. If this happens it means there is too much food in the tank. Simply stop feeding them until it clears up and then start feeding them once a week. The food in the packet should last a good while but if you start to run low, you can purchase more sea monkey food at Toys R Us, pet shops or online several places. You can also get anything you need for them plus additional supplies at the official sea monkey website.

Fun Facts about Sea Monkeys

  • Sea Monkeys are born with one eye but as they grow they form two more eyes and end up shedding the one baby eye eventually. So according to which stage of life they are currently in, they could have either one, two or three eyes!
  • Many think Sea Monkeys are just brine shrimp but they are actually not the same. They are in the same family but do have differences. Brine shrimp do not live near as long as sea monkeys.
  • Male and female sea monkeys mate to make babies just like other animal species but if a male is not present, some females can make babies without a male. The process is called meiotic parthenogenesis.
  • Sea Monkeys actually breathe through their feet!
  • Sea monkeys live up to 2 years and can get up to 3/4 inches long.

I hope you have found this useful. You can check out youtube for lots of sea monkey videos and I found seamonkeyworship.com and seamonkeysrule.info helpful as well.

Enjoy your sea monkeys!

        I had them as a kid as well; so naturally had to buy them for my kids when they were younger. They were fun for me when I was a kid and I remember checking to see if they were there every day. Oh, the memories. :) Great hub that brought back a piece of my childhood.

        A great idea for entertaining the child. Many children don’t even know the name of sea monkeys. With this hub, that memories of childhood has also perished. In the age of modern technology, the procedures are also easy and wide in range. So you can gift your child with sea monkeys in different occasions and take part with them in making sea monkeys. Thus you will be able to build up a good and close relationship with your child which is becoming rare nowadays. So go to the nearest shop around you, buy the things needed for the task and enjoy with your child.

        I've never heard about Sea Monkeys but I find it very interesting and educative so that children learn about patience and some scientific terms like parthenogenesis. This pet has very interesting fun facts that made me keep smiling when I read them .

        kidscrafts- Thank you for the votes up and positive feedback :) Yes, he did enjoy getting them started.. I don't think he quite understood what was going to happen but he was excited to see them swimming all around the tank a while afterwards :) From what I understand, they can mate and I've also learned now that the adults lay eggs before they die so I guess they can just keep going and going! Thank you so much for dropping by and I'm glad to hear that this hub sparked your interest :) Maybe there will be some sea monkeys in your future ?!

        Stephanie Henkel- Oh yes, it was a lot of fun... and it's fun watching them grow. I'm surprised at how fast they have grown.. We could easily see them swimming around the tank about 4 days after we added the "live eggs"... I don't remember them growing this fast when I had them years before! Thank you so much for the positive feedback, votes and for sharing this :)

        lady rain- Wow, that is awesome! I didn't know the adults laid eggs before they died.. Sounds like we don't ever have to run out of sea monkeys if we don't want to. I did gather from my research they don't require much feeding and that they are pretty self sufficient. Thank you for sharing this info! It's nice to get some first hand advice and information from someone experienced with raising sea monkeys. Thank you!!

        vespawoolf- I know what you mean.. if only they could look like they do on the packaging! I never did know what they were exactly either until I researched for this hub. Like you, I became attached to them and I was horrified that day years ago when the tank fell and emptied onto the carpet :( When I saw them at WalMart, I just HAD to get them... so it has been fun reliving the experience with my son. Glad I could bring back some nice memories for you :)

        Bill, Thank you so much! I had these when I was little and when I saw them at Walmart I know I just HAD to get them for my little one. At first he wasn't impressed but now that they are visible and swimming in the tank, he has taken more interest :) I am going to post a pic as soon as I can after they get a bit bigger... just to give readers an idea what they look like. I wish they actually did look like what is on the packaging, LOL! Thank you so much for dropping by... hope you had a wonderful weekend as well!

        Very interesting Jamie! Your son must have love the experience to start up everything! So if I understand well, the life expectancy of your sea monkeys is 2 years but you might get some babies so your son might enjoy to see a few generations of sea monkeys?!?

        Voted up and interesting!

        I have three tanks of sea monkeys which I have been keeping for several years. The adults sea monkeys lay eggs before they die and the babies usually hatch in the warmer months. I don't feed them very often as the sea monkeys eat the algae growing in the tank. The tanks are like mini eco systems on their own.. pretty amazing!

        I also had sea monkeys when I was a kid and loved them. At first I was disappointed they weren't an underwater royal kingdom as advertised on the box. Still, I grew attached to the transparent little creatures. I always thought they were brine shrimp. How interesting they're in the same family but not exactly the same thing. This brings back nice memories. What a fun gift for the kids!

        I didn't even know what they were. I've never heard of them. I must live in some sort of vacuum, out of touch with the real world. LOL How fascinating, and what a cool project for a kid. Well done, Jamie, and thanks for the education. Have a great weekend my friend.
