I breed dwarf crayfish and while it's true crayfish can stay submerged some
species leave the water at night to feed on plants and scavenge dead animals.
Big crayfish are a real danger to fish. The bigger varieties of crayfish will
uproot and eat plants but the extent of the damage depends on the species.
Dwarf crayfish eat detritus, algae, and really love earthworms cut up into
small pieces they are good scavengers and will not harm fish but many fish
will eat them when they shed their shells to grow. dwarf crayfish are among
the least aggressive species of crayfish and usually don't eat each other
unless they lack other food.
