Habitat
- Requires large aquariums (minimum 180 gallons) with ample swimming room and structured live rock.
- Mature and stable aquarium conditions essential for successful long-term care.
- Plenty of caves, crevices, and hiding spots required to mimic their natural reef habitats.
- Strong filtration and moderate water circulation crucial for maintaining excellent water quality.
Fish Care
- Preferred water temperature: 74-79°F (23-26°C).

- Sensitive to fluctuations in water parameters; regular monitoring and diligent aquarium maintenance necessary.
- Monitor closely for signs of marine diseases and parasites; early detection and prompt treatment crucial.
Compatibility
- Semi-aggressive; best housed with similarly sized and temperament-compatible fish.
- Not typically reef-safe; likely to nip at corals, sponges, and ornamental invertebrates.
