CATDOLL : CATDOLL: Can crayfish be kept together with fish in an aquarium?

Crayfish can be mixed with fish in the fish tank, but the fish cannot be too big, otherwise they will eat the shrimp. There should also be water plants to facilitate the shrimp to hide when changing their shells. Usually, small tropical fish such as tetras should be selected, because they live in the upper and middle layers of the water body and are very active, so they will not be scared or hurt. Black-shelled shrimp can be selected for land shrimp. If the fish are relatively large, it is best to separate them if mixed. You can use an isolation net to separate the upper and lower water bodies.
