Sea-Monkeys® Ocean Zoo Neon - World's Only Instant Pets® - Assorted Colors - Ages 6+ (Pack of 1)

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.

I wish I could give 0 stars but I can’t, so this gets 1. My brother ordered these same sea monkeys for my daughter and they never hatched after 2 months of waiting. I chalked it up to me not following the instructions correctly. I purchased these sea monkey’s myself as a birthday present for my niece and again, they still didn’t hatch. SCAM!

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.

The sea monkey kit arrived in good condition, I ended up with the teal colored kit, and it’s a very good color for a male. The plastic of the kit felt very durable and of good quality, standard sized sea monkey kit. I filled it to the water line with distilled water, added packet 1, waited a little bit over a day and added the packet 2, within a few hrs I started seeing the tiny little brine shrimp small as dots wiggling around in the water. Will be waiting til Thursday of next week to feed em from packet 3. I used had a kit back when I was a kid in the 90’s and it’s still as much fun now as an adult! Really brought me back to the coolness of watching something hatch and appear like magic! Reading the manual that comes with the kit was very interesting and educational to learn about the variety of brine shrimp.

Nostalgic, brine shrimp, fun!

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

I wasn't sure if the lill srimpy boys where gonna come to life but after a week and a bit I started to see movement, they're thriving now and I couldn't be happier.

I half expect this to be an old stock and with low hatching rate but was surprised! I had like perhaps 20 or more hatched. I don't know how long they will survive but I've had them for 4 days and they've done well. I bought another one on the way and I think this version is a newer batch so it is still fresh

Very disappointing Christmas presents. Bought four packets and none hatched.
