I'm in search of an algae eater for my 40L tank. Currently I have a 6 month old short-fin albino bristlenose, but this will obviously need to be moved into a larger tank eventually. Is there any type of algae eater that wouldn't out grow the tank size? It does have a fair problem with algae, and the bristle nose was in control of it until I moved other fish into the tank? The tank is kept at a consistent 26oC
