The Bursa Triggerfish, once it is comfortable in your aquarium, displays an active interest in it's evironment and it's keeper. But be sure you keep it well fed. Also make sure it has plenty of space, and a cave or rock formation where it can retreat to. The Bursa Triggerfish 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 surgeonfishes, groupers, and basses. Some eels and puffers can be appropriate too.
Members of this family have acquired their common name 'triggerfish' from the characteristic locking and unlocking of their first dorsal fin. Normally the dorsal fin is positioned in a flat groove on the top of the body. It can however, be locked in the upright position in order to wedge the fish into some crevice in which it has taken refuge. This keeps the triggerfish from being removed from the crevice and eaten.
Description: Triggerfish are relatively poor swimmers, most of the time they move with undulating wave motions of the dorsal and anal fins, only using the tail fin for emergencies! Triggerfish have teeth that are very stong and often stick out, which is ideal for eating shelled invertebrates and sea urchins. Don't put a Triggerfish in an aquarium with invertebrates! When eating a Crown of Thorns starfish, the trigger will first blow it over onto it's back in order to get at the soft unprotected underbelly.
Care and feeding: In captivity these fish will eat almost everything that is offered and should be fed everything like live foods (brine shrimp), frozen foods, flakes, squid, shrimp (regular or river), and even chopped earthworms.
