Balistoides conspicillum, commonly known as the Clown Trigger, is the most commonly seen Triggerfish in the hobby. Its color pattern makes it an easily recognized species. The fish is black, the lower half of the body covered with large white spots. A yellow speckled area is present on the dorsal area of the fish. The mouth is surrounded by a brilliant yellow patch.

This species is also known as Balistoides niger. They possess the ability to lock their dorsal spines in a raised position as a defense against larger predators. The Clown Trigger is among the most aggressive of all Triggerfish species.

Tank Setup

This fish needs an extra large aquarium due to their large adult size and active lifestyle. Tankmates must be chosen with care; the Clown Triggerfish is an aggressive species known to take over all other tankmates. Any crustaceans kept in the aquarium will be devoured. Provide plenty of open swimming space, a sandy substrate and good lighting. A good-sized cave will give the fish a natural area to sleep.

Feeding

Balistoides conspicillum has a very powerful jaw that it uses to crush its prey. This carnivore should be fed a variety of foods such as mollusks and crustaceans. Once accumulated to the aquarium they can be persuaded to eat most anything.

Water Chemistry

A salinity between 1.023-1.027 and temperature between 75-79 degrees F is recommended. If kept in proper conditions the fish lives a long and active life.

Breeding

Breeding information is unknown. The male of the species is larger than its female counterpart.
