I bought a crab a few weeks ago. I was wondering if anyone else has any crabs and wanted to know if you feed them anything? Thanks!

it depends on what you have in the tank. Mine are my reef cleaners and they dont get fed. They just eat the detritus and uneaten food including algae. I did feed my decorator crab(saltwater) fish once but it was messy. For freshwater, I had a crawfish that ate dead feeder fish. I would assume other crustaceans will go for the same opportunity.

Make sure you give them brackish water and access to air. Recently lost one because I didn't think it mattered
