### ⭐⭐⭐⭐⭐ Nice, Affordable Little Gift
*by L***D on 20 January 2024*

I got this for my niece who wanted sea monkeys. It was easy for her to follow (age 7) and the monkeys appeared! They are pretty easy to look after, especially as she forgot about them at times. Great value too.

### ⭐⭐⭐⭐⭐ Sea monkeys
*by T***Y on 25 June 2025*

Excellent quality product thank you. We now have new pets

### ⭐⭐⭐⭐ only two survived, then by the 3rd week a further 5 hatched
*by C***Y on 7 March 2022*

Getting everything you need in this pack makes it good value for money. On day 5 there were roughly 20 sea monkeys swimming around. I fed them on day 5 then, unfortunately, after day 7 only 2 sea monkeys survived. Right before week 3, I moved the tank to a warmer room and now I see 5 newly hatched sea monkeys. Very happy with this unexpected twist :)
