chinese algea eater
Chinese algae eaters make good scavengers in aggressive tanks. Particularly when you have a hard time putting anything else in that tank. I have a golden algae eater in a tough 220g cichlid tank. Salvini, Green terror, texas cichlid, gold flake pike cichlid, etc. THere is not a single fish in there he can bully, heh. He also doesnt really compete for territory with the other fish and if one of the other fish decide to mess with him, he can hide and is very elusive.
