Appearance

The black durgon has a distinctive appearance, characterized by its deep, oval body and a predominantly black coloration. When a good deal of light is applied directly on the fish, it can reveal a number of hues, but in most lighting situations, it appears a black velvet.

Habitat

Black durgon fish are commonly found in shallow coastal waters, typically around coral reefs and rocky areas. They prefer depths ranging from about 1 to 30 meters (3 to 100 feet), where they can find plenty of food and shelter.

Diet

These fish are omnivorous, feeding on a variety of foods. Their diet primarily consists of algae, coral polyps, and small invertebrates. By grazing on algae, they play an important role in maintaining the health of coral reefs.

Behavior

Black durgon fish are known for their bold and curious nature. They can be territorial, especially during the breeding season, when males will defend their nesting sites against intruders. They are also known to exhibit playful behavior and may interact with divers.

Environmental Indicators

As a reef fish, the black durgon is an important indicator of the health of coral reef ecosystems. Changes in their population and behavior can signal shifts in environmental conditions.

These characteristics make the black durgon fish an important and interesting part of Hawaii’s marine biodiversity!
