Overview

This species is found in tropical waters around the world and is usually seen in aggregations, swimming high above the reef, often with schooling zooplankton feeders. It is also found associating with large floating rafts of Sargassum, a species of brown algae.

Family: Balistidae

Other common name(s):

  • Black Durgon
  • Black Oldwife
  • Blackfish

Native range:

Habitat: The Black Triggerfish is common around oceanic islands and is usually found on inner and outer reef crests, usually near the slope or drop-off to deeper waters.

Maximum length: 50 cm (20 in)

Minimum aquarium size: 912 L (241 gal)

Water: Marine 24 °C (75 °F) - 28 °C (82 °F)

Feeding

Mixed diet of meaty foods, including chopped seafood, mysid shrimp, frozen preparations, and flake foods. Feed at least three times a day.

Aquarium Compatibility

Because it feeds mainly on floating plant material and zooplankton, it is a possible candidate for the reef aquarium. However, in nature, and in captivity, it will occasionally nibble on sessile invertebrates. It may also harass ornamental shrimps that are introduced after it has become adjusted to its captive home.
