Hop to next section Husbandry Information
FeedingNot a fussy eater, most foods are accepted. Bloodworm and sinking catfish tablets are best, but once established will eat flakes at the surface. Larger fish will take cichlid tablets / doromin.
FurnitureFloating plants are a good idea although this fish will live happily on most set-ups.
CompatibilityPeaceful and not predatory, although larger specimens can be downright boisterous at feeding time.
Suggested TankmatesIdeal for mid to large sized community tanks. Best kept with other similarly active bottom feeders such as Brochis, most Botia loaches. They are even tough enough to be kept with Labeo 'sharks' and similar. This is a good catfish for an active, lively set-up featuring, for example, barbs or rainbowfish.
BreedingBubblenest builder. Well conditioned pairs should spawn readily, but a large water change should prompt spawning of a more reluctant pair.
