I have a 75 gallon tank with a leopard bushfish, african butterfly fish, soon to be butis butis (crazy fish). Possibly a dwarf pike cichlid or a smaller non dwarf pike cichlid but havent decided yet. Besides the point. I am looking for help on finding a suitable pleco (6" - 10") carnivore or algae eater that could live in the tank with these guys? and if a electric blue crayfish is a good or bad idea?
