Haha, well, since he's in a cichlid tank I don't have that problem. There are no plants (real or plastic), just a bunch of rocks with algae, and good hiding places. I knew about the excessive amount of poop from my bristlenoses, which are affectionately named Poopy and Big Poopy. It'll take a little extra cleanup on my part, but I love watching plecs, so it'll be worth it.
