Overview

  • Native to the Indo-Pacific, commonly found in coral reefs, rocky ledges, and reef drop-offs.
  • Distinguished by its vibrant red and white body with vertical bars and an elongated dorsal fin.
  • A hardy species known for its perching behavior, often resting on corals and rocks to observe its surroundings.
  • Typically seen in solitary or small group settings, preferring locations with ample hiding spots.
  • Best suited for aquariums with stable water parameters, live rock structures, and peaceful to semi-aggressive tankmates.

Feeding

  • Carnivorous, primarily preying on small crustaceans, shrimp, and tiny fish in its natural environment.
  • Thrives on a varied diet of frozen mysis shrimp, brine shrimp, and finely chopped seafood.
  • Readily adapts to high-quality pellet and flake foods formulated for carnivorous marine species.
  • Should be fed multiple small meals per day to sustain energy levels and promote digestion.
  • A protein-rich diet supports its natural predatory instincts and maintains vibrant coloration.

Habitat

  • Prefers coral reef environments with moderate water flow and an abundance of rocky hiding spots.
  • Often seen perched on coral formations, using its strong pectoral fins to remain stable.
  • Aquarium setups should include live rock to provide natural shelter and perching areas.
  • Requires high-quality filtration and stable water conditions to prevent stress and disease.
  • Providing shaded areas alongside open swimming space allows for a balanced habitat.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) to ensure a healthy environment.
  • Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
  • Requires regular water changes and consistent maintenance to thrive.
  • Not considered fully reef-safe, as it may prey on small shrimp and other invertebrates.
  • Providing an aquascape with various rock formations supports its perching behavior and territorial tendencies.

Compatibility

  • Semi-aggressive and territorial, especially towards similar species.
  • Compatible with larger, robust fish such as tangs, wrasses, and angelfish.
  • Should not be housed with very small fish or slow-moving invertebrates, as they may be considered prey.
  • Best kept in tanks with well-defined territories and ample rockwork to minimize aggression.
  • Providing adequate space and hiding areas reduces stress and encourages natural interactions.

Aquarium Behavior

  • An observant species that spends much of its time perching on elevated rock surfaces.
  • Frequently seen scanning its surroundings before making quick movements to capture food.
  • Becomes more confident and interactive over time, particularly during feeding sessions.
  • Providing structured aquascaping with open swimming areas and perching spots enhances its behavior.
  • Over time, it may recognize its caretaker and exhibit curiosity, especially during feeding times.
