this is one of the first fish I introduced to my tank, was 6", now 12".
very active, n always hungry. I like the way it swim, swinging the tail, slapping other fish if they didn't look out for it.
importantly, it feeds off parasites from its suckers. so non got ill so far.
but now it has overgrown, I don't think I can house it for long. gonna search for q bigger house for it.
