My pleco gets all the spoils from everyone else's eating... but he's a big boy, and isn't ever satisfied. He'll even go up to the top and eat floating pellets sometimes. Usually I drop on a bunch of shrimp pellets for him, but god they make a mess of my tank. He loves bloodworms, but so does everyone else, so he never gets many. I drop some cooked zucchini in there now and then, but he shreds it, and my tank looks like a war zone for hours afterwards. He'll also eat krill, but with the same issue - floaty krill bits all over my tank. Anyone recommend something he can munch on without polluting my tank?
