Like some other triggers, this species can be quite shy at first, but usually becomes very brazen in time. This species is not extremely aggressive. Most individuals can be kept housed in a community aquarium with similarly-sized fishes. You should add your Niger trigger to the tank after the more passive species have settled in. Provide this fish with plenty of hiding places, like a piece of branching or foliose coral or a chunk of live rock with an appropriate-sized hole for it to go into if threatened.
