Yellow bullheads range from the Great Lakes to Texas. Yellow bullheads make nests in mud bottoms to spawn. Both parents then guard the nest. The eggs hatch in less than a week. The young bullheads then school i tight schools which are guarded by parents.
Yellow bullheads can be distinguished by the round to flat tails. Yellow bullheads have white barbels below the mouth, black bullheads have dark barbels below the mouth and the uncommon brown bullhead has barbels light colored at the base, darkening to grey or black at the tips and a lightly spotted / mottled body.
