The African bullhead, Lophiobagrus cyclurus, is a small claroteid catfish endemic to Lake Tanganyika. It hides among rocks by day and forages after dark, and it lives in most communities of Tanganyikan catfish and cichlids, though very small fish will be eaten. It is rumoured to secrete a poisonous mucus when stressed that can kill other fish in the aquarium, which is one reason to house it in as large a tank as possible.
Distribution
EditHabitat
Write a noteEditIt hides among rocks during daytime hours, emerging to forage under cover of darkness.
Aquarium size
Write a noteEdit75 ∗ 30 ∗ 30 cm30 ∗ 12 ∗ 12 in - ~68 litres~18 US gal bare minimum, although larger is recommended (see below).
Maintenance
Write a noteEditShould be housed in a Lake Tanganyika biotope setup, with piles of rocks arranged to form caves in which it can seek refuge. Provide areas of open water for swimming. Dim lighting will encourage it to be seen more often.

Diet
Write a noteEditOmnivorous and unfussy. Frozen, live and dried foods are all accepted.
Behaviour and compatibility
Write a noteEditAlthough very small fish will be eaten, it will live happily in most communities of Tanganyikan catfish and cichlids. It can also be kept in small species groups without problems.
Sexual dimorphism
Write a noteEditUnknown.
Reproduction
Write a noteEditRarely bred in aquaria but it has been achieved. Apparently, the breeding pair lay their eggs in a rocky cave, and the eggs hatch in around 4-5 days. No extended parental care has been recorded, so if you do get a spawn, it may be wise to remove the parents/fry to a separate tank.
Notes
EditAn interesting addition to the Tanganyikan community that is not often seen in the hobby. There is a rumour that this cat can secrete a poisonous mucous when stressed that can kill other fish in the aquarium but this has not yet been 100% confirmed. It may be wise to keep it in as large an aquarium as possible just in case. There are currently just 4 species of Lophiobagrus described. All are from Lake Tanganyika.
