Like the Bursa Triggerfish, be sure you keep the Brown Triggerfish well fed. Also make sure it has plenty of space, and a cave or rock formation where it can retreat to.
We are not sure exactly what the scientific name for the Brown Triggerfish is. The texts previous to 1990 list this and the Bursa triggers in the genus Suflamens, while newer texts list the Bursa as Balistes. We are assuming that the Brown Triggerfish is also listed as Balistes now, since we can't find it in any of the newer texts.
Fish in this genus have been known to be possible troublemakers. Ways to keep a peaceful tank is to house appropriate fish together that have similar needs and can hold their own. In this case larger protein eaters such as groupers, surgeonfishes, and basses. Some eels and puffers can be appropriate too.

Maintenance: Feed all kinds of live, frozen, and flake foods. Best to feed small amounts several times a day. We generally feed squid, shrimp (the same kind people eat), mussels, and all kinds of chopped up fish.
