Overview

  • Native to the Indo-Pacific region, commonly found in coral reefs and lagoons.
  • Recognized for its deep orange to red body with a single white stripe behind the eye.
  • A hardy and territorial species known for its symbiotic relationship with sea anemones.
  • Popular among marine aquarists due to its bold coloration and adaptability to captivity.

Feeding

  • Omnivorous diet, consuming plankton, algae, and small invertebrates.
  • Readily accepts high-quality marine pellets, flakes, and frozen foods such as mysis shrimp and brine shrimp.
  • Supplementing with enriched foods enhances coloration and overall health.
  • Multiple small feedings per day ensure proper nutrition and energy levels.

Habitat

  • Commonly found in warm, shallow reef environments with plenty of coral cover.
  • Prefers stable water conditions with moderate water movement.
  • Thrives in aquariums with live rock formations and anemones, though anemones are not required.
  • Well-suited for community reef tanks but may become territorial in smaller spaces.

Fish Care

  • Optimal water temperature: 74-82°F (23-28°C).
  • Ideal pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
  • Hardy and disease-resistant, making it suitable for beginner aquarists.
  • Regular water changes and proper filtration help maintain long-term health.
  • Providing hiding spots and an anemone (if desired) ensures a stress-free environment.

Compatibility

  • Can be aggressive, especially towards other clownfish species.
  • Compatible with a variety of tank mates, including tangs, wrasses, and angelfish.
  • Should not be housed with highly aggressive species or larger predatory fish.
  • Best kept singly or as a mated pair to avoid aggression.

Aquarium Behavior

  • Active swimmer, often seen exploring its environment or hosting an anemone.
  • Can display defensive behavior when protecting its territory.
  • Forms strong pair bonds and exhibits fascinating social behaviors.
  • Providing an environment with hiding spots and open swimming areas supports natural behaviors.
