I bought one labeled as a "baby royal pleco". After a few months I've come to find that it is actually a clown pleco. He has since cleaned my entire tank of every speck of algae. I have a 55 gallon planted tank, and so far the only plants he has eaten have been a red rubin sword and I think it's called taiwan nymphoides. Aside from that he also attacks any leaves that aren't perfectly healthy, namely a few of my swords. He never touches the healthy leaves though, so it's fine.
