No, that's not it. It looked kinda like a common pleco but was all spotted instead of just motled. You could clearly see all the spots and they were a white color, not bright white but like an off white and the body was a deep green, like a dark hunter green or something. The dorsal fin sticks up really high when it moves around (thus the name I'm guessing) and it seemed shorter then the common, kinda squished. They also seemed to have a longer nose then the common and these crazy horn-thingys just in front of the eyes. Does this help any?
