The Bursa Trigger fish is also known as the Black Patch Trigger fish. This fish has a face that is half white and half yellow; it also has a pencil-thin moustache and a colorful mask across the eyes. Another distinguishing feature is a large black circular area on the abdomen.

The Bursa Trigger fish is a beautiful and popular fish in the aquarium hobby. The fish has a yellow body with markings that make it look like a work of abstract art.

This species is highly aggressive and will readily eat smaller fish. It should only be kept with other aggressive fish.

In the wild, Bursa Trigger fish are most commonly found in shallow reef edge areas with sandy bottoms. They are found both in seaward and lagoon reef areas, where they feed on tunicates, mollusks, crustaceans, corals, fish, and sea urchins. As with all trigger fish, they are not reef safe. This is because they are destructive toward other fish and invertebrates in their aquariums.. Bursa Trigger fish are considered to be fairly hardy. They have strong teeth and jaws and may chew through items in their aquariums. Any inanimate object in the aquarium should be sturdy and well anchored. Often trigger fish will rearrange objects in the aquarium.

Bursa Trigger fish are laterally compact, though they can distend their undersides to make themselves bigger. Using their large first dorsal spine that can be locked into place, they may wedge themselves into tight places of their aquariums and are quite difficult to remove once they are in such a position. The first spine is the largest and strongest and cannot be collapsed by pressing on it. However all of these spines can be folded down by pressing on one of the smaller spines.

Maximum size: The Bursa Trigger fish grows upto 9 inches in length.

General Size: This fish generally comes in size varying between 3 to 9 inches.

Minimum Tank Size: A 75 gallons or larger aquarium provides good environment for Bursa Trigger fish.

Tank Conditions: The Bursa Trigger fish should ideally be kept in temperatures between 72 and 78 degrees Fahrenheit. A pH value of 8.1 or 8.4, and a specific gravity of 1.020 to 1.025 should be maintained. When kept with invertebrates, the specific gravity range should be 1.020 to 1.025, for the invertebrate species. In a fish only aquarium, the specific gravity should fall between 1.020 and 1.023.

Habitat: The Bursa Trigger fish occurs on coral reefs of the Indo-West Pacific and in Hawaii. In Australia it is known from the offshore reefs of north-western Western Australia and from the northern Great Barrier Reef to northern New South Wales.

Feeding and Diet: The Bursa Trigger fish is a carnivore that can be fed a mixed diet of shrimp, squid, clams, fish, and other meaty fares suitable for carnivores, as well as marine algae and vitamin-enriched herbivore foods.
