Product Description

The Original Sea-Monkeys - Worlds Only Instant Pet

Sea-Monkeys, tiny brine shrimp invented in the 1950s, remain in suspended animation until you activate them using the provided kit in their aquarium.

These creatures offer an exciting educational experience, allowing both kids and adults to witness biology in action. From hatching to growing, observing their life cycle in real-time is captivating for all ages.

They make an ideal pet for kids, teaching them valuable lessons about responsibility on a manageable scale.

Tips for Sea-Monkey Success

1. Water temperature: Check the temperature chart for the best hatching time. Warmer water (around 75-80°F) helps eggs hatch faster..

2. Egg anatomy: Some eggs have thinner shells and hatch quicker, while others have thicker shells and take longer. It's natural biological variation.

3. Healthy light: Put your tank near a window facing north for good, but not direct, light. This helps algae grow, which Sea-Monkeys eat.

4. Feeding: Only feed Sea-Monkeys when the water is clear. Too much food can harm them.

5. Evaporation: If you notice the water level decreasing in your tank, refill with bottled drinking water which is at the same temperature as the tank water.

Title: Great price and lots of fun
Review: This was really to use. We used this with the little live pets aquarium. My son’s sea monkeys lived 6 months! We were shocked. He enjoyed feeding them daily and eventually seeing them come to life. Very easy to use and my son had months of fun with this.

Title: Junk Product. Eggs Out Of Date
Review: After a previous try at starting a sea monkey colony that my 3 year old knocked over and killed I bought this product to restart my tank. The eggs just didn't hatch. I followed the procedure just like I did the last time but this time after a few days of no activity in the tank I became concerned. Sure enough the eggs did no hatch and no sea monkeys ever developed. The egg pack was expired and me and my son were both very disappointed. Avoid this product at all costs you're better off with brine shrimp eggs at your local fish store. Do not buy this product, it's functionally a scam and I regret purchasing this pack. It gave me the same feeling you get buying an item at the grocery store only to get it home and see it was expired at the time it was sold to you. I hope this product is removed by Amazon before anyone else is taken advantage of.

Title: Forget the Sea Monkeys kit, get this instead
Review: After having a mixed experience with the tiny 10oz Sea Monkeys kit I decided to use a far larger tank (1.5 gallons) and the results were astonishing. It's very easy to mix your own water (just get Instant Ocean salt, distilled water and a cheap hydrometer at 28-32 ppm), a 10-15 watt adjustable heater @ 74-80F (this is important or the eggs will not hatch), a small air pump* and off you go. Do not use any type of filter as brine shrimp are filter feeders and the food needs to stay in suspension. Brine shrimp are very adaptable to water conditions so you don't need much to provide optimum conditions, just consistency.They grow much faster than with the tiny kit tank and started reproducing by the second week. I now have over 20 adult critters and countless babies three weeks later. The advantages of a larger tank are numerous: it's easier to keep a constant temperature, it is much less stressful to the shrimp when doing weekly 10% water changes and it's easier for the kids to see them. Using your own tank is more expensive than the $20 kit (I spent about $75) but you'll have a self-sustaining tank that can last for years, not 3-4 months like the kit.*(edit) Do not use an airstone, the tiny bubbles produced can interfere with their respiration. Use an open airline tube with a adjustable valve to provide 2-3 bubbles a second. This will provide enough turbulence to promote oxygen exchange without unduly disturbing the shrimp.*July 2024 Update* The tank is still going strong with 100 or so adults and hordes of little ones. Brine shrimp will slow down reproduction once the tank reaches its limits so you needn't worry about overcrowding. Tank algae is a problem once you have a large population so weekly 10-15% water changes are extremely important to reduce nitrate levels. No one likes mucky green aquarium water.

Title: Very easy and exciting
Review: This is definitely something great to start out with. I had an old sand art container that was perfect for these guys. We had the water temp set at 75 and a little oxygen hose with a slow but steady bubble rate so they have enough and I wouldn't forget to air rate the babies manually, so it was a steady temp for more of a hatch success rate along with oxygen,Which was the best thing to do. Read the directions very carefully and the results can vary, however, in the right environment your rate for a whole colony goes up. I want to say most of not all of the eggs we ended with hatched, all being different sizes, which are adorable. My beta eats these and sits right next to the container so he is consistently eyeing them. But so far so good, they're active, love light, and are hypnotizing. I would like to know where i can obtain water purifier just by itself to a tank cleaning.

Title: SEAMONKEYS R THE BEST.
Review: I was born in Houston Texas in the 70's. Iam 51 years old & i have LOVED SEAMONKEY my entire life. ♥️ I have 6 Grandkids and I have bought them for all them. I could tell rt away who was gonna be Lazy! Lol lol 😆 ❣️. One of my Grandson's i couldn't get him to feed then 2x while his Paw Paw & i went on a mouth cruise. SAD! If i had one complaint is that they need to come out with some new Habits. I saw a utube video where this guy had a fish tank & he had it full w/them, LED lighting, bubble 🫧 stick. It was AWSOME. So that's why i got a few extra packs. Now as iam sure ya'll can see i have 2 tanks ya'll offer & so far they are doing great 👍🏻.

Title: These are not good kits!
Review: I ordered one for a science experiment. It came taped up and when opening, the eggs were green slime. I requested a replacement package, it also came taped up, but there was nothing but white powder in the eggs package, and when I added it to the conditioner water, it put a green slime at the bottom of the container. After waiting 2 days, there are no shrimp in the container.Now before anyone comes at me and tells me it is operator error, let me point out that I have hatched these eggs, from other vendors naturally, successfully many times over many years. Science experiments for students.

Review: I bought these in August to make a custom sea monkey tank. My tank is 0.5 gallons, but ended up being a bit less than that once I filled it with water. The packets are good for 10 oz to 12 oz of water, so I used 5 packages for my tank. I put all of the packets in my tank following the instructions carefully, saw a couple of baby sea monkeys and then they died and nothing else happened. The tank had also turned quite green after adding the egg packets. I was bummed, but thought I'd leave the tank to see what happened. Saw one more hatch a while later, it died, so I left it again. Fast forward to early November when my tank was over half evaporated and I was waiting for it to fully evaporate so I could try refilling it to trigger a second hatching (as I saw mentioned online). Looked in and to my surprise there were two almost adult sea monkeys in there with a few more babies besides! I was in a bit of a conundrum as the tank was now over half evaporated, and I was planning on pulling out the gravel on the bottom as I read after the fact that they can get trapped in that and die. I ended up pulling out all of the gravel even with them in there, surprisingly they made it through fine and then I started topping up the water incrementally so as not to change it too quickly on them. They're doing fantastic now, and there are loads of babies coming along! I'm so thrilled. So don't give up if your tank doesn't do anything right away. I didn't feed my tank at all since first starting it, though I was aerating periodically. I still haven't fed my tank actually, because the water is still cloudy as there was so much food in there from the start. I can't comment on the more recent reviews of bad packets, mine came in perfect condition and were shipped with Canada Post with no issues.

Review: I don’t know if they all come like this but mine was already opened and then taped back together ? Everything’s inside but it just seems odd for something that’s supposed to be new.
