Blue Small

What do I put the fish in a tank with two small blue cancer?

I was thinking of putting maybe two or three fish with them.

Crayfish eat all other fish. You have to hide a large tank with plenty of room to fish. Get those who like to hang at the top the aquarium. The crabs will remain at the bottom, so maybe a little more. Look for zebra and leopard danios. These are small, fast, and how the top of the aquarium.
