||Occurs in pools and sluggish
runs over soft substrates in creeks and small to large rivers.
Also found in impoundments, lakes, and ponds. Rarely enters brackish
waters. A nocturnal feeder that feeds mollusks, insects, leeches,
crayfish and plankton, worms, algae, plant material, fishes and
has been reported to feed on eggs of least cisco, herring and
lake trout. Juveniles (3-6 cm) feed mostly on chironomid larvae,
cladocerans, ostracods, amphipods, bugs and mayflies. Can tolerate
high carbon dioxide and low oxygen concentrations and temperatures
up to 31.6 °C although experiments show upper lethal temp.
to be 37.5 °C; resistant to domestic and industrial pollution.
Has been observed to bury itself in mud to escape adverse environmental
conditions). Aquarium Care: Bullheads adapt well
to aquarium conditions but do bare in mind that they does grow
big along with the capable size of its mouth! so if housing with
other temperate fish you would be better going for larger stock
such as yellow perch or the larger sunfishes. Putting them in
with goldfish is not a good idea, not for the poor goldfish anyway!.
They adapt well to most aquarium conditions as long as you give
them a cave of some sort and to keep the lighting down to a minimum
for viewing purposes.
