Black Bullhead - Ameiurus melas
The black bullhead is the most common bullhead in Montana. It is an introduced species with scattered populations statewide but primarily concentrated in small ponds and backwater sloughs of eastern Montana. Black bullheads are extremely tolerant of high water temperature and turbidity and low dissolved oxygen, thus making them a good fish for certain ponds. Their feeding and spawning habits are similar to channel catfish. Newly-hatched bullhead fry swim in a large mass which looks like a moving black ball, attended by the parents, often providing a unique curiosity to a first-time observer. They seldom exceed 1 pound in weight and thus are rarely a desirable game fish in Montana waters.
Rear edge of spine in pectoral fins smooth or nearly so. Membranes between fins darker than rays.
