Wafers
These wafers were specifically developed for the hard to feed plecostomus and other algae eating bottom feeders. This food can be a great supplement for herbivorous fish. Drop one or two in at night when the tank lights go off for your bottom feeders. This way they won't have to compete with the top dwelling species for the wafers.
