Black Durgeon

The Black Durgeon is a striking triggerfish species distinguished by its solid jet-black body with subtle blue or green iridescence visible under aquarium lighting. White lines run along the bases of the dorsal and anal fins, providing an elegant contrast against the dark body. This species is found across all tropical oceans, making it one of the most widely distributed triggerfish in the world.

Unlike many triggerfish that are notorious invertebrate predators, the Black Durgeon is considered one of the most reef-safe members of its family. In the wild, it feeds primarily on zooplankton, algae, and drifting organic matter rather than benthic invertebrates. This planktivorous feeding habit makes it far less likely to harass corals, clams, or ornamental crustaceans compared to other triggerfish, though it may still occasionally sample small shrimp or snails.

Despite its reef-safe reputation, the Black Durgeon can be quite aggressive toward other fish, particularly in confined aquariums. It establishes territories vigorously and will chase or nip at tankmates that encroach on its space. A minimum tank size of 180 gallons is recommended to provide adequate swimming room and reduce territorial conflicts. This species is remarkably hardy and adapts well to captivity, making it an excellent choice for aquarists seeking a unique triggerfish that can coexist with corals.
