Overview
- Native to the Indo-Pacific, commonly found in coral reefs, rocky overhangs, and coastal lagoons.
- Easily recognized by its bright red body, white horizontal stripes, and large, reflective eyes.
- A nocturnal species that remains hidden during the day and becomes more active at night.
- Has a peaceful temperament but may show slight territorial behavior around its chosen hiding spots.
- Best suited for aquariums with ample caves, rock formations, and subdued lighting.
Feeding
- Carnivorous, primarily feeding on small crustaceans, worms, and zooplankton in the wild.
- Thrives on a diet of frozen mysis shrimp, brine shrimp, finely chopped seafood, and high-quality marine pellets.
- Readily accepts prepared foods but benefits from occasional live food supplementation.
- Should be fed in the evening or at night to mimic natural feeding habits.
- A varied diet ensures proper nutrition, strong immune function, and vibrant coloration.
Habitat

- Preferred pH range: 8.1–8.4, with a salinity level of 1.025–1.026 (about 33–35 ppt).
- Requires regular water changes and consistent maintenance to prevent stress-related illnesses.
- Reef-safe but may consume very small ornamental shrimp and delicate invertebrates.
- Providing a structured environment with hiding spots helps reduce stress and encourage natural behaviors.
Compatibility
- Generally peaceful but may become territorial around its preferred hiding places.
- Compatible with clownfish, tangs, wrasses, and other reef-safe species.
- Should not be housed with highly aggressive fish that may harass or stress it.
- Best kept in tanks where it has adequate hiding spaces and is not outcompeted for food.
