Underwater World Science Kit – Live Aquatic Creature Hatching Box for Kids Age 6+

This is currently the cheapest Aqua Dragons kit with a tank, and gives clearer viewing than most other brine shrimp tanks. I removed the plastic wrap around it as I'm using an aquarium airstone in the tank and found that "salt creep" was getting underneath the wrap. It's easy to remove and improves visibility too. The instructions that come with them usually work well, and are more effective and educational than Sea-Monkey kit instructions. The egg packet also contains a far larger number of viable eggs than Sea-Monkey kits. As with rearing any live animal, I would recommend doing a little research before starting however - watching a couple of short YouTube videos on raising brine shrimp will give you a good head start . They need a bright and warm spot, so you can use a heat mat/mini aquarium heater if your space is too cold, and you can use a small grow light if the space is too dark. An air pump is not needed, but improves conditions and saves having to manually "aerate" (really just mix the water and put food particles in the water for feeding). I'm kinda weirdly obsessed with these types of brine shrimp kits and have tried many different brands and kits over the years - Aqua Dragons are currently the best brand IMO and this kit is the value for money compared to the others at the moment too :).

I bought these for my partner (40 going on 12) as a bit of fun for christmas after she mentioned that they looked "really cool" after seeing them online. We've had them going eight days now, and I'll be honest I really didn't think we'd get ANYTHING to hatch, as the whole thing sounds very gimmicky. However 2 feeds later and plenty of air pumping we now have what do actually look like cute little water dragons. Our top tips, for successful dragons are (especially for parents...) 1. Ignore the instructions, and throw them in the bin (seriously) 😉 2. Use fresh bottled water at room tempriture to start with (NOT tap water) 3. Pour the whole sachet of dragon eggs into the tank and pop the lid on. Place the tank for the first two days in the living room, or somewhere its not too hot or cold. Not near a window to start with! (LEAVE THEM ALONE) 4. After two days we put our hatchlings in our kitchen window, which is slightly cooler than our living room. You could just see them if you looked really carefully. 5. Supervise your kids, if you overfeed or try and rush the hatching process, it will fail like so many other people have said. Have patience. 6. IMPORTANT... Five to six pumps of air at a regular times per day to air the water with the pipette provided. 7. Hopefully on day 8, like us you'll be able to see little dragons develop, you will see they have now formed dragon like tails!!! Regarding food, we didn't even feed the hatchlings until three days after hatching, and only used a level spoon of the food (with the spoon provided) it totally covered the top of the water. You don't really need to feed them again until all of that has dissappeared after two or so days. Hopefully that little guide will help with parents and kids frustrations at nothing happening 😉 All in all value for money, a great novalty present that has everything you need to grow water dragons. The tank doesn't leak, for what you should use, the food should last week's, and by day eight you'll lose count of how many of these fascinating little creatures there are. Would recommend and would definately buy again for someone as a novalty present. Parental supervision definately required and lots of patience.

I luckily had put no creatures in there, yet... . But when my Aqua Dragons aquarium fell about 60cm onto a stone floor, it broke down. Also, water can easily run out of it with a lid like that. The colour of the aquarium is lovely. I would still recommend getting a small glass tank or a plastic tank designed as a small animal carrier. This aquarium can get knocked over too easy, I am afraid. When I added a thermometer to my original aquarium, it also tore away the layout with the nice Aqua Dragons design that is not printed onto the aquarium itself but more for marketing reasons and part of the packaging. What's more, it does not reveal what is inside the eggs sachet and the nutrition sachet as of detailed nutritional ingredients used. I would like to give 3.5 stars, also because the set is containing everything needed but a decent aquarium... . Rounding up to 4 stars because I love watching sea creatures and the product is better advertised than Sea Monkeys. Before you buy them, these are LIVING animals. If you go on holidays, get a pet sitter. Don't discriminate against those creatures simply because they are made of less cells than a human being, and certainly don't let them drown in a toilet bowl alive. Thank you! These animals are not a toy but make a nice science project that may keep you busy for many, many months, if you keep on feeding them and raise new generations, you can make this a hobby.

Bought for my son and he loves them! He was upset at first because I didn't read the instructions properly and I used tap water instead of room temperature bottled spring water so I ordered another one for him straight away assuming that I messed it all up before they even had a chance to hatch, I ordered another set but I thought I'd keep the original one by the sunlight on the windowsill just incase they'd still hatch and omg they did (it took around 4/5 days for them to hatch if I remember correctly. Good job I gave them a chance cos look at them go lol! They seem to be thriving in the tap water I used lol but I'll be reading instructions properly in future, my son loves watching them swim and grow

I placed mine directly into a bigger tank I had to buy 2 lots though(you can buy the eggs separately).they kept dying in the original tank they give you hence why I used a bigger one The bigger your tank the more eggs you need They look amazing Breeding often and now I have tiny babies On the video you will see some green stuff at the bottom it is normal over time it will appear (never remove it ) the water looks greenish due to adding extra water in the tank so it lifted up some of that green algae at the bottom. Highly recommended You will need 2 or 3 sachets for bigger tank When you pour the water in the tank I recommend to leave it to settle for 24 hrs before adding the eggs otherwise they will die over time most of them Do not over feed them they only need a tiny amount and never feed them daily If you over feed them your water will become cloudy . If this happen don't feed them at all until your water becomes clear again . They will carry on eating the spare food in the tank. The water in the tank will start to evaporate over time. Use distilled water to add some more or use kettle water boil it and leave it to cool down . Once the water is cold use the plastic pippet provided to add water slowly . I do not recommend adding water too fast ... sea monkeys are fragile creatures and a sudden change WILL kill them . Add water carefully and most important really slowly , hence why I use the plastic tube provided . I do not recommend to keep them in that tiny tank they sell . Sea monkeys breeds fast and you will have lots of babies in no time so really soon you will need a bigger tank if you use the one provided in the starter kit

Doesnt work followed instructions and no living bodies from the eggs

These were a great activity to do with the kids but unsure if its something we did but they didnt turn out as good as we had hoped. It was still worth buying due to having fun while setting them up but I feel they are harder to work than you would think. Nothing hatched but again was still great fun to do.

My 10 year old son loves them. Very easy to set up, use bottled water only not tap water! We added the eggs on 6/12/25 and they hatched on 8/12/25 they are now becoming more visible as of 12/12/25 as you can see in the video, very active little things, we are excited to watch them grow. We oxygenate the tank every day and feed them a tiny amount every 2-3 days as instructed. We kept them in the airing cupboard the first 3 days to hatch as its nice and warm. If you follow the instructions you should have no issues like us.

Jätte bra! Nöjd son

so good perfect design thank you so much I really appreciate that 👍😊😊

Facile à installer et très sympa de voir l'évolution. Ils vivent assez longtemps pour en profiter

super easy to grow, simple, small amount of care other than blowing bubbles into tank and feeding them

Nos ha ido genial!! Han nacido un montón 😊 En las instrucciones viene muy bien explicado todo el proceso.
