My 90G inherited my daughters common pleco, and I know it will get to big, but I like the looks of the fish. Is there a different species that looks close and stay in the 5-6 inch range?
All plecos look rather similar (in an appealing way) to me. How about a bristlenose, rubberlip/bulldog or clown pleco (although the last isn't much of an algae eater it is really cool looking, the first two do a bang up job)?
