What do yabbies eat?
Pet yabbies, such as blue claws or electric blue marrons, will happily eat prepared crayfish pellets. For some variety, also give them pieces of whole frozen fish, a garden worm, frozen beans, carrots or a piece of mussel. Make sure each yabby has a cave to feed in and never feed meat. Meat will pollute your water and this will kill your yabby. Make sure you keep a calcium block in the tank at all times.
