Crayfish, also called crawfish or crawdad, any of numerous crustaceans (order Decapoda, phylum Arthropoda) constituting the families Astacidae (Northern Hemisphere), Parastacidae, and Austroastracidae (Southern Hemisphere). They are closely related to the lobster.

They will eat many commercial fish foods including sinking algae wafers, shrimp pellets, and many freeze dried or flake foods. It's a good idea to include a lot of fresh foods in their diet as well.
