my son was excited to get this kit and watch his sea monsters hatch. we followed all of the instructions and days later nothing... we waited a week later- still nothing. two weeks later it was clear there was no life in the water so we dumped everything out - very disappointed :(

followed instructions as written and eggs never hatched. Checked it daily. started over a week later with the other half of the packet and still no luck. either they need to rewrite their instructions or have a better quality check.

Kit itself is nice but nothing hatched (even after 1.5 weeks) and I followed instructions to a “T”. Legit don’t even know if there ever were any eggs in the pack cause all I saw was dirt in the plastic pouch for eggs.

Brought this kit and made sure to monitor the water temp and used distilled water as my tap water is too chlorinated having learned from having many fish in the past. Great little aquarium for the price.

My kid was so disappointed. Nothing hatched no matter what we tried. Followed the instructions to a T. He used his own Christmas money. What a waste.

I bought this for my niece a couple weeks ago and my sister told me how every morning she'd run right into the kitchen to check on her fish. When they hatched she started naming all of them. 🤣

I bought this for my little boy, who is all into dinosaurs and prehistoric creatures right now. He is so fascinated by this water tank full of eggs, that he gets up every morning and runs to check on it. Well finally today, would you know it, an egg hatched and we had to celebrate, LOL! Such a simple inexpensive toy that brought smiles to my little boy. As you can imagine, next on his wish list is a fish tank full of fish!
