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.
