Better than Sea-Monkeys!
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 :).

Definate adult supervision required if you want them to hatch and grow!
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.

My son loves them
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

Disappointed
Ordered these for my class and we were so excited. Unfortunately, even after following the instructions to the letter, not a single egg hatched. Very disappointed class of 7 year olds.

Was fun to seat up
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.

10 year old loves his little dragons
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.

Dragones vivos y coleando
El producto funciona perfectamente, los dragones salieron al tercer día, los oxígenamos mediante una piedra atomizadora cinco minutos al día, y los alimentamos cada tres días, están muy bien , las fotos son antiguas por lo que ahora están mucho más grandes, a mi hijo le encantaron

Tolles Set für meinen 5 jährigen
Die Urzeitkrebse leben jetzt seit ca einem Monat bei uns. Mein Sohn hat Riesen Spaß daran sie zu beobachten und zu füttern. Er füttert sie alle 2-3 Tage und macht mindestens einmal täglich Sauerstoff mit der beigelegten Pipette ins Wasser. Wir haben lange überlegt was für Wasser wir benutzen, weil ich gelesen habe, dass bei einigen nach 3 Tagen alle tot waren. Deutsches Mineralwasser scheint laut mehreren Quellen nicht geeignet, da Mineralien zugeführt werden. Leitungswasser scheint auch zu gehen, aber ich war skeptisch, da dies von Ort zu Ort ja auch unterschiedlich ist. Am Ende haben wir nicht-abgekochtes Quellwasser außer einer Quelle im Wald genommen. Das Wasser wäre auch Trinkwasser geeignet. Ab und an muss man Wasser nachschütten, weil es verdampft. Auch hier nehmen wir Quellwasser. Das funktioniert super bei uns. Die Krebse sind ganz unterschiedlich groß und flitzen durch den Behälter. An die 10 Stück sind schon richtig groß, schätze so 7mm. Man kann sie gut mit bloßem Auge erkennen. Am Anfang hat mein Sohn eine Lupe benutzt. Mit der konnte er schon nach 4 Tagen erste Krebschen sehen. Wir empfehlen das Set ganz klar weiter :)
