Description
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. 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.

Disappointed, but maybe my fault?
Size: Small
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.

no no no
Size: Small
only 2 sea monkeys came out of this (thankfully one boy and one girl) and altho they did have babies, all the babies disappeared shortly after being born and the female passed away as well leaving only one lonely daddy sea monkey who passed about a week later. it was more of an overall bummer and Rollercoaster if emotions than a learning experience or pets. I wiloyldnt buy these again ever, especially not for the expensive price.

Loved these since I was a kid
Size: Small
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.

Initial results are very promising!
Size: Small
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.

Easy instructions but would add a couple of my own that go against the product directions
Size: Small
I had a fun idea with my niece to get us both sea monkey kits, so that we could grow these and study them and talk about them together. It was her first experience with sea monkeys (or brine shrimp). I recall having sea monkeys for long periods of time growing up and was actually really excited because I remember being fascinated by them and really surprised by how big they got. This one was for me. I ordered a nicer one for my niece. Everything worked out much better than I expected at the beginning (at the beginning is the key phrase here). Wait for what happens. This did not come in a box. It was actually just the little tank with its lid zip-tied down and the instructions and packages inside. I was somewhat disappointed in that. I followed the instructions by first preparing the water and adding packet one. No issues. At the allotted time, and I think I waited an extra day just to be on the safe side, I added only a very tiny amount of package 2 containing the eggs due to a warning from one of my family members who remembered doing this as a kid and that one full package of eggs produced far too many sea monkeys and so they died. I’m thankful that I listened, because even just a tiny portion of the eggs in the packet produced a LOT of sea monkeys. I can’t even imagine what it would’ve been like if I dumped the whole package into that small tank…. After this, you have to wait 5 to 7 days for feeding. I would probably recommend five days and I would not recommend using the actual spoon. The spoon doesn’t even have a little scoop in it so it’s kind of confusing on how much to use, but I think that you should basically use about as much to fit on the end of a toothpick at the beginning. My problem was that I miscalculated and put a little bit too much of the food in, which created a massive algae bloom and killed off my entire tank. This is not a product problem, it’s a user issue. I added too much food….I blame myself and that has nothing to do with the rating. I was sad. I have since ordered another package with the three pack set of the water preparation, eggs, and food, and I’m hoping to start over again with the same tank. You live and you learn.!

Did not disappoint!
Size: Small
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.

Very few eggs
Size: Small
Egg pouch does not have as many eggs as it used to. I had two hatch, given it got cold at night, and then maybe another two within a month. Ordered separately a new egg pouch, so many more eggs in the egg pouch ordered separately, over 20 hatched. I would not get this tank again, or make sure to also order the eggs separately.

It failed twice in a row
Size: Small
I first bought Sea Monkeys around 1994 and they lived for many months and even had their own eggs. I have bought more Sea Monkeys over the years and always succeeded in keeping them alive for a long time. Then I bought this set on Amazon. (I was a little worried about the negative reviews but figured that many people had not followed the instructions correctly.) I followed all the instructions to the letter. The eggs hatched but died within 3 or 4 days. So I contacted Sea Monkey and they told me that some companies are selling old batches of eggs. They wanted me to wait for 3 weeks to see if any Sea Monkeys would hatch. After 3 weeks I contacted them saying that none of them hatched and after a couple more weeks they mailed me a new set of eggs. Again, I followed all the instructions perfectly and I saw a bunch of Sea Monkeys within minutes of adding the eggs to the treated water. Then 3 or 4 days later they were all gone. I don't know if they changed something or perhaps they are shipping old batches but I would not recommend these.
