My daughter had a different version of a sea monkey aquarium and it tipped very easy and she lost her sea monkeys. This one is perfect for girls and it doesn't tip easily. Easy to feed. The other aquarium had magnifying spot on it and this one does not. I went to the Dollar Store and bought a magnifier for it and that works perfectly. You really only need the magnifier for it when the sea monkeys first hatch. We have had it up and running for two weeks and you can see them easily with out using a magnifier.
