The Clown Pleco is Peckoltia Vittata; also known as the Tiger Banded Pleco.
They are my favorite Pleco's. If you have plenty of driftwood in your tank, and not too much open space between, then you should see plenty of the Clown Pleco.
Yeah, that's what Ive seen the name under mostly. For years I thought that's what mine was. (Cuz it was the closest of the two pic's I had at the time ) But I see so many peeps referring to Clown Plecos, I wondered if it was just being applied to all of 'em. I think mine's actually a L205. I really like him.
