About the Atlantic Sea Cucumbers (S)

Atlantic sea cucumbers are slow, peaceful sand sifters that swallow sand and digest the detritus and film coating it, leaving the bed cleaner. This listing is a small one. It needs a mature tank with a wide bed of fine sand, and every pump intake and overflow must be covered, because an injured or dying cucumber can release a toxin that kills fish.
