Well, there is no such thing as a "suckermouth catfish." I assume you mean plecostomus, in which case one would outgrow your tank, as would clown loaches. If you are looking for bottom feeders, consider cory cats, otos, kuhli loaches, or a rubberlip, clown, or bristlenose pleco (these stay a little smaller).
