his picture depicted below of the 'Brown
Bullhead' is of a 20" individual owned and coveted by coldwater
catfish enthusiast, John Henderson of the Northern Area Catfish
Group of Great Britain, now renamed The Catfish
Study Group (UK). This fish has won numerous awards in the
coldwater catfish section.
When small the 'Brown Bullhead'
is quite tolerant of other species, but in a short matter of time
when it starts growing you would not be able to keep any other
fish in the same tank as they would be viewed as lunch!. Warning!
do not put in with your prized goldfish, or prized goldfish
This catfish is raised commercially in the United States and widely
stocked in ponds and Lakes. The flesh of this catfish is orange-coloured.
Ameiurus nebulosus prefers deeper and clearer parts of lakes
than A.melas, the "Black Bullhead", and is therefor
more susceptible to falling water conditions in the aquarium than
One thing they do have in common with catfish from the Asian continent
is that they possess 4 pairs of barbels (chin barbels dusky or
black) unlike the catfish forms of South America who in the whole
have three pairs. This can be a good way to identify your catfish
if you are not too sure from where it originates from.
There is now moves afoot by the U.K. Government
through the Ministry of Agriculture, Fisheries and Food (MAAF)
to impose restrictions on some coldwater species like the above
mentioned Brown Bullhead, due to the dangers of introduction
to native waters and the threat to its occupants through disease
and predation. In other words you could be paying up to £30
for a license to keep them.
Update: As of November 1998 in the U.K.you must have
a licence to keep the above species. This licence is now issued
free, but does take a few months to process. For more information

luster by reflected light, often with cloudy blotches. Belly whitish
to grey. Iris yellow. Anal fin variously marked, usually mottled

Bullheads adapts 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.
In its natural habitat in early spring the
female lays her eggs in the substrate in shallows that are warmed
by the spring sun, or under an overhanging bank, the eggs are
laid in balls and adhere firmly to the bottom, they can number
into the thousands. The black young hatch out after 8 days and
are cared for by the male.
Adults eat just about everything, pellet
food, tablet food, frozen bloodworm, earthworms, shrimps and prawns.

nebulosus: Clouded, dark or mottled.
