Howdy, Just got a rubber lip pleco to try to solve my algea problem without getting a pleco that will grow 2 feet long. The only problem is the little guy seems to only be interested in hiding under a rock ornamate and not in getting busy on the algea. How good of cleaners are these guys supposed to be compared to common pleco? Is it just me, or do they seem much more shy? Are they too shy to get to work?
