I agree with Ian... One Bristle nose and a small school of cories...The "perfect" cleanup crew. :thm:2 male Bristlenose will probably fight - a pair will probably breed.
Personally I would just get one BN, they are good algae eaters, wont hassle your other fish, and wont outgrow the tank. Just they often spend all day sucked onto the bottom of a hunk of driftwood, and only come out after "lights out". Then you still have space for a small school of Corys.
