Overview

The Bursa triggerfish is smaller than most triggers but genuinely aggressive, especially toward smaller or slower fish. It is best with a little experience.

Did you know

The Bursa triggerfish's half white, half yellow face is split by a dark line, so it looks almost like a mask. With the large dark patch low on its body, it is one of the easier triggerfish to identify at a glance.

Caring for the Bursa triggerfish

Give a Bursa triggerfish a tank of at least 125 gal (473 L), with sturdy caves and secure rockwork. It is a determined digger and rearranger, and it retreats into a crevice at night or when threatened.

Keep the water at 72 to 79°F (22 to 26°C) and a pH of 8.1 to 8.4. Feed a varied carnivore diet of squid, krill, clams and small fish. Include hard-shelled foods to keep its teeth worn down.

Keep only one per tank, since it does not get along with other triggerfish outside a very large system. Choose robust tank mates rather than anything timid. It is not venomous, but it bites and grunts audibly when it feels threatened.

The Bursa triggerfish is not reef safe. It readily eats crabs, snails, bivalves and other invertebrates.

Good to know

Sufflamen bursa is a triggerfish in the family Balistidae. Its large black belly patch gives it the alternate name blackbelly triggerfish, and it is also sold as the boomerang or scythe triggerfish. Like other triggerfish, it can lock its first dorsal spine upright, using a second, smaller spine as a catch. Wedged into a crevice this way, it is very difficult to remove by force.

In the wild

The Bursa triggerfish lives on reef flats and slopes across the Indo-Pacific, from the surface down to about 120 meters. It forages over rock, rubble and sand for crabs, mollusks and other invertebrates.
