Sea-monkeysSea-Monkeys® On Mars - World's Only Instant Pets® - Ages 6+ (Pack of 1)

The media could not be loaded. This sea monkey kit is super cool. We’re now on our third generation of sea monkeys FROM THE FIRST PACKET of eggs!! A few things that have worked for us: We feed them every 4-5 days and only about half of the TINY scoop. If you over feed them, it’ll mess up the water and can kill them but if you underfeed them, they’ll surely die. Our first ‘generation’ hatched about five, I think, and two of them survived into old age (haha). They swam in perfect synchronization for like three days at one point (it was really neat and kind of astonishing, to be honest) swimming and doing little turns and flips all over the tank. We keep ours on the windowsill above the kitchen sink in a west-facing window with partial shade (in NW FL) and they do well there. I write the date on the outside of the tank with a dry erase marker each time I feed them so not only do we not over feed, but when I’m washing my hands or dishes I inadvertently see the date and notice if it’s time to feed again. The first time I accidentally went six days we lost one of the two originals. But the remaining one survived alone for quite awhile (several more months)… until it happened again and we lost the second of the two originals. Twice before this there were new tiny little babies but I’m fairly sure the bigger ones ate them when they were still tiny. After we lost both ‘Flotsam and Jetsam’ I went to dump the water out and saw another baby!! So ‘he’ grew up (Roscoe this time, after our late dog) and had MORE babies. You can barely see him (or her) in the video but there’s the big one (Roscoe) and a teeny tiny one (yet-to-be-named). The brown thing on his backside is poop. It eventually falls off. Lol. I’m trying to feed a tiny amount every 3-4 days this time so hopefully Roscoe doesn’t eat the new guy. I think they also eat some of the algae that naturally grows on the surfaces over time. Three times now, when the water level dropped I took a small amount of filtered water from the fridge, left it out overnight to let the excess chemicals evaporate, and topped off the tank. It didn’t harm any of them. Trust me, the deaths have all been when I realized, “oh $&@! It’s been six days since I fed them!!” They’ve definitely been a really neat experience for my 4 y/o (and the rest of the fam!) and well worth the money considering we’ve had several rounds of hatchlings now! I hope this review helps. If you’re thinking about getting this sea monkey kit for kids 3-9 y/o, I highly recommend it! I even sent one to my friend’s kids in Wisconsin and they enjoyed it immensely.

I love it! This is a great experience to share with my children.

I have had my sea monkeys for 6 months and still going. I have a few, but they produce babies. I do take a small dropper to remover very little debri at the bottom. Never replaced water. Still very clear. Just a few drops when water evaporates.

The tank itself is cute but my eggs were complete duds. This isn't my first go at raising Sea Monkeys, cryptobiosis fascinates me, but these eggs failed to hatch at all. If I remember right Schilling guarantees the eggs to hatch or they replace them so I will update this if they send replacements.

The tank is awesome. However pack #1 had mostly all leaked out and was wet. So I used my own marine salt. Next the #2 pack with the eggs & more salt in it appears bad/old because I could only count 3 sea Monkeys hatched after a couple days. Very low hatch ratio. I ended up buying a tube of be be brine shrimp eggs which many hatched out within 18 hours. If you buy this do it for the tank, and don't expect much out of packs #1 and pack #2. The food pack may be good, too early to say.

So cool and fun for kids and adults

Egg packet was full of green liquid and unusable. The food packet was also damp. I went to a craft store and bought a basic sea monkey kit (purifier, eggs, food) rather than return the item.The tank itself is pretty unique and fun. I’ve had luck raising these little guys in the past, so i have no doubt they’ll look cool in this environment. You should use a heat source (heat mat/mini heater) if you raise them in water that falls below 68 degrees. I’m knocking off two stars because the ruined/wet egg packets are a common problem and because i paid $7 for the replacement kit.

my sea monkeys lived for a while the set up was my favorite and it was exactly what i remembered from when i was a kid
