Size 420mm or 16.5" SL. Find near, nearer or same sized spp.
IdentificationThe yellow, brown and black bullheads look very similar to each other, but the yellow bullhead is easily distinguished from the other two species by their yellow or white (vs. dusky or black) mandibular barbels.
SexingMales have an elongate genital papilla. Breeding males have greatly expanded head muscles.

FeedingIn the wild, the yellow bullhead feeds on crustaceans, aquatic insects, worms, beetles and small fishes. Not a fussy feeder in captivity, taking both prepared and frozen food readily. Will eat smaller fishes if given the chance.
FurnitureInhabits streams and lakes with sandy bottoms. Best maintained in an aquarium of 55 gallons or larger. Provide ample hiding places.
CompatibilityPeaceful both with other fish. Conspecifics may establish a dominance order based on size. Should not be kept with tankmates small enough to be eaten.
Suggested TankmatesLarger North American native fishes like sunfish and yellow perch, given its propensity for eating smaller tankmates.
BreedingBreeding occurs primarily in the late spring and early summer. Shallow nests are prepared by one or both parents, by fanning the pelvic, anal and caudal fins, shoving material out with their snout, or picking up material in their mouth and carrying them away from the nest. During spawning, the fish lie side by side, facing in opposite directions and twisting their caudal fins over the eyes and head of each other. About 650-7000 eggs are laid, with the eggs, which are yellowish and are about 2.5-3.0 mm in diameter, hatching in about 5-10 days. The male then guards the nest, fanning the egg mass, yawning widely over the nest, or even taking the egg mass into the mouth (possibly to aerate them). Upon hatching, the young cluster together in a mass at the bottom of the nest, and the adult fish may approach the mass and agitate it with their barbels; this apparently moves the larvae near the bottom of the mass to its surface. The fry are guarded until they reach about 25 mm TL.

Not very common in the area. Naturally, grew quite rapidly, inhaled several Gambusia affinis, Fundulus kansae, and one CAE. Was in a 25-gal tank with two turtles, did fine with them and helped keep the tank clean, along with 2 I. punctatus. Gave all three cats to a friend, after which they quickly developed ich and did not recover =(", (19) cowturtle, (20) TerriV, who also notes: "Gently takes LG pellets from my fingers! :-)", (21) slayer5590, (22) juanitoman, (23) Blackbullhead, (24) Hardmancatfish, (25) Nativeguy, who also notes: "Wild caught juvenile, eating frozen food 3 day s later".
