Chaetostoma cf. thomsoni -- it looks like a pleco. the lfs sold it to me as a rubberlip pleco. it's got a nice, olive green coloring with white spots on it's head area. does anyone have one? can you tell me what to expect? i placed it in my 55 gal and it seems very happy. he's about 2 inches. i was told that it might reach 4 or 5 inches at maturity.
