Common name: Black triggerfish

General information

The Black Durgon Triggerfish, Melichthys niger, is a distinctive and robust species known for its deep black coloration with blue and purple hues on the edges of its fins. This triggerfish can reach up to 50 centimeters in length and is recognized for its rhomboid body shape and strong, dorsal spine, which it uses for protection by locking itself into crevices.

In the wild, Black Durgon Triggerfish are solitary and territorial, often found patrolling their reef habitat. They are omnivores, feeding on a variety of foods including algae, zooplankton, and small invertebrates.

Care

In the aquarium, Black Durgon Triggerfish require a large tank with plenty of swimming space and rockwork to simulate their natural environment. They are hardy and adaptable but can be aggressive, especially towards smaller or more docile fish. A varied diet of meaty foods and some vegetable matter will keep them healthy and their colors vibrant.

Reproduction

Breeding Black Durgon Triggerfish in captivity is rare. In the wild, they are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic before settling onto the reef.

Habitat

Black Durgon Triggerfish are found in tropical and subtropical waters across the Indo-Pacific region. They prefer clear, outer reef slopes and drop-offs, typically ranging from 2 to 75 meters in depth. Their distribution spans from East Africa to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, and south to Lord Howe Island.
