Some species benefit from additions of periphyton-covered rocks to their
tanks.  Two species where I live-- the mountain sucker and chiselmouth--
feed on this material in their natural habitat and pretty much require
it if they are to be tank-reared.  They'll graze on those rocks and
ignore other foods.  The chiselmouth has specially-adapted mouthparts to
accomplish this.

I wonder if hog suckers would be easier to rear if they were fed this
