Depends on your crayfish.
My pets were Louisiana crawdads. These guys are generalists — omnivorous, able to live in a variety of water quality (by pulling air into the gills when living in low oxygen situations), able to live in a variety of water temperatures and flow rates. They can make short overland trips too.
Some other species of crayfish aren’t as hardy.

I am trying to compare the niche of a fish and a crayfish help me please?
