Taxonomy
- Family: Balistidae
- Genus: Balistes
- Scientific name: Balistes capriscus
Habitat
FishBase reports a Western and Eastern Atlantic distribution. The species occupies bays, harbours, lagoons and seaward reefs at depths from 0 to 100 m, typically 0-55 m. FishBase records a broad temperature range of 9-26.2 °C (mean 17.8 °C), reflecting its occurrence in cooler waters than tropical triggers.
Tank requirements
- Minimum tank volume: 1000 L (about 264 gal)
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- GH: 8-12 °dGH
- Water flow: high
- Lifespan: 10-20 years
Diet
This carnivore feeds on benthic invertebrates, including molluscs and crustaceans, and other bottom-dwelling organisms according to FishBase. In aquaria it is offered meaty marine foods twice daily.
Compatibility
FishBase notes the species is usually solitary or in small groups and competes with other species for food. It is not reef-safe and is kept only with other large robust fish such as large angelfish and tangs. Avoid ornamental shrimp, snails, crabs and small fish.
