Sea-Monkeys Ocean Zoo Neon

I love sea monkeys so much. I find them a very nostalgic part of childhood and wanted to get my kids hooked into them also. Mine came damaged but still usable and they did not hatch. Not a single one! I’ve never had that happen before. I’m not sure if it’s related to the time of year or just a bad batch? Nonetheless, I am disappointed. But rest assured, sea monkeys are awesome and if your batch takes off, they are so fun and simple to take care of. EDIT: Updating review from 4 to 5 stars - Happy to report that my sea monkeys hatched out of nowhere 2 weeks after adding the eggs! I didn’t do anything other than leave the water chilling in the same spot for two weeks. I almost considered dumping and trying again a few days prior to seeing some activity, so I’m very glad I didn’t lol. So far, we only have 3 tiny little guys, but they’re doing well. So if you think your eggs are a bust, just give it a little more time! It does say in the pamphlet that it can take up to 3 weeks for all eggs to hatch, but I didn’t expect that I wouldn’t have a single hatch until 2 weeks. Nonetheless, I am pleased! I’m thinking most people who reported no hatching just didn’t give it enough time or provide the best conditions.

When I first bought this, I was expecting something a little bigger, but that was probably my fault. But that wasn’t the main problem, I did exactly what the instructions told me to do, you know thought up with water, wait until the water is room temperature, pour the water purifier in, wait 24 hours or more before pouring the second pack in. But when I poured in the second pack, I didn’t “see tiny white “dots“ that are struggling to swim against the direction of the current.” And I believe that was because I didn’t stir it, so that’s what I did. Throughout the day I was constantly checking to see If any of them at hatched. But sadly I didn’t see any. It kind of looked like everything that came from the packet sort of just floated up to the top at the surface of the water, I don’t know what the deal about that was. This product is probably expired, I wish I could get my money back but at the moment I’m still trying to figure out how to refund this. I hope the people looking at the reviews right now are not going to buy this because it would be a bad purchase.

No damage to contents. Packets #1 and #2 sealed and dry. I haven't opened #3 yet. I bought a small in-tank heater, add 12oz of regular spring (not mineral) water, and waited until it was heated to 78F. I added packet #1, and inserted a small aerator to mix in the contents. Over a 24hr period, I saw no early shrimp activity though I did see some eggs. After 24Hrs of adding packet #1, I added packet #2 and again aerated with the device I used earlier. After about 12hrs I checked and saw some activity! After 24 hrs, more activity! I once again aerated. I don't plan to aerate for a bit. I'll let them grow some. In addition to the in-tank heater, I have the tank sitting under some timed grow lights to stimulate algae growth. I had initially intended to wait for awhile, after adding the spring water, but before adding any packets, to have some algae already available, but then I wondered if adding the salt would cause them problems. I decided I would rather algae establish in the environment it will exist in. Also, I just got impatient! 😂 As it stands thus far, this product and seller have provided and fun and reliable product. All of the issues I have read elsewhere, were nowhere to be found here. If you are interested in growing pet, hybridized, brine shrimp, this is a great option, IMHO. I would strongly suggest you get a very small in-tank heater, if your ambient temps aren't going to be a steady mid-70s, and get a small plant grow light on a timer, either way. If you can get a healthy algae colony going, you can really cut back on explicit packet feeding, plus the living algae will be more nutritious. At that point, you'll mostly need to just stay on top of water re-fills. Regarding water, for the love-a-Mike, please don't use tap! Just get some bottled natural spring water from your local grocer, or, at worst, some distilled water. You're only adding a couple of ounces per re-fill so even a quart or liter would last for some time. So, all in all you're probably looking at the cost of this tank plus small heater and small plant grow light. And if you have a low to mid 70s stable ambient temperature, you could do without the heater. I will likely update in a week or two. UPDATE: I'd say a good 15 or so made it to young adulthood. I moved them to a prepared .5gallon tank, with heater and bubble stone. It had some algae and some previously transferred bit of water from this original tank. Now, about 10 days after move, only a couple have passed, and the rest have been doing nothing but swimming, eating and making bebes! A few unhatched eggs from the initial setup hatched upon transfer to the larger tank. They are now 1/4-1/3". And there are scads of those super small pin-points swimming around. I'll know in a week or two if the larger volume and existence of algae (plus the packet food) is enough to allow some to grow further. If I end up with "Loads O' Monkeys", i'll update with a photo.

Fun as always. I had these as a kid and have had several tanks since I was a kid. The instruction book is a little different from way back when... a little more rooted in science and a little less in fancy (although those old instruction books had a lot in them!). Overall, it's very easy to set up a tank and get it going - you just have to be patient. Eggs hatch at different rates and sea monkeys will have babies, so sometimes you might think you've only got two adults out of the deal, but if you're patient (and follow directions closely) you'll soon have a tank of all different ages swimming around. It looks nice - I keep it on a windowsill in the kitchen by the sink. Plastic. Has little magnifying lenses built into the side. Overall fun.

As description said. I had this exact one as a kid in the 90s and all the accessories like the watch and I was obsessed. Needless to say I hyped it up and my daughter was very disappointed. ***Edit because we left the tank there for a couple of weeks and lo and behold some more eggs hatched and they are thriving

The sea monkey eggs hatched as expected! Really follow the rules about using bottled water and regulating the water temp. I’ve learned my lesson in the past but not taking these details seriously. Fun for all ages. Low maintenance. Educational! A fun gift for elementary or middle school aged kids. Nostalgia unlocked.

My daughter wanted me to buy these for her so I did it was pretty neat watching the little shrimp grow but sadly only one lived for a little bit maybe a month or so!!! So if you don’t mind spending your money and time with these little shrimps then you should get it but if not then I would suggest not to buy it!!

I did the first one filtered water used the purifier waited about 36 hours and added the eggs. They were kept at a consistent temp all started hatching and then 3-4 days in all were dead. Got a replacement set used bottled water purifier waited again they all hatched and I am left with one single sea monkey. I don’t remember them being this hard to keep alive back when I was a kid I got this kit to do with my daughter and it has just been a huge disappointment.

Chegou em ótimo estado antes do tempo previsto.

Just buy the £10 version. The picture is deceiving and it’s lucky to stand 10cm high. £43 for this product is a joke

Purchased as a gift for my 10 year old daughter. She was so thrilled and as was I to share a childhood nostalgic memory with her! Surprised that they did hatch on the first attempt (took a few days and made sure to follow instructions carefully ie use bottled water) and they grew! What a cool experiment. We have some eggs left over as we didnt do the whole batch just in case but are excited for round 2. The first batch died after a couple months because my girl forgot to keep the water fresh and not get stagnant and possibly forgot to feed.. so this has been a great lesson in responsible pet care and the consequences of improper care. Hopefully we do better in the next batch! We'll worth the purchase!

Not happy gave it to my Granddaughter for Christmas and they did not work very upset little girl

Any parent or aunt will know that it isn’t an easy task, finding gifts for young children whose interests change like the speed of wind. This was very well received by my nieces who are 8&9. A gift that the parents also support due to the educational angle. I couldn’t be happier with my purchase. I’ll definitely buy it again for other kids in future.
