You legend thank you x

It's an egg tumbler for mouth brooding cichlids.

However, these should not be used unless the female mouth brooding cichlid regularly eats the eggs, and most mouth brooding cichlids don't eat their eggs.

If you artificially hatch and rear any cichlid fry, they miss out on the maternal bond they develop with their mother and they don't learn from her. When the baby fish grow up and breed, they have no idea how to be good parents and regularly turn into egg eaters. This happens to all types of cichlids ranging from African Rift Lake cichlids, South American cichlids like angelfish and discus, and Central American cichlids.

Good job @eatyourpeas!
