The store I got it suggested frozen daphnia, but one cube is a lot of food, and the other fish ignored the cube so far, so I am concerned about polluting the tank. I wondered if I just slightly overfed the fish if the crab would hunt down the excess. "He" seems super active at searching the tank, already.
Typically they will come out at night and clean up the tank, eating whatever unmentionable gunk they happens upon. They'll eat sinking pellets, bloodworms, flake food, just about anything. If you feed a few sinking crab pellets shortly before lights out then yours should get plenty of food. You don't need to feed daily.
