Overview

  • Found in the coral reefs of the Red Sea and Western Indian Ocean.
  • Recognized by its four distinct horizontal lines running along its body.
  • Often seen darting among coral structures, making it a lively addition to reef tanks.
  • Exhibits cleaning behavior, occasionally removing parasites from other fish.

Feeding

  • Primarily feeds on small invertebrates, plankton, and reef-dwelling organisms.
  • Readily accepts frozen mysis shrimp, brine shrimp, and high-quality marine pellets.
  • Offering a varied diet enhances its coloration and overall health.
  • Multiple small feedings per day keep it active and well-nourished.

Habitat

  • Prefers reef environments with abundant coral structures and crevices for hiding.
  • Requires an aquarium with live rock to establish a secure territory.
  • Moderate water flow and stable conditions mimic its natural habitat.
  • Thrives in mature reef aquariums with a diverse ecosystem.

Fish Care

  • Optimal water temperature: 75-81°F (24-27°C).
  • pH level: 8.1-8.4, with a specific gravity of 1.023-1.026.
  • Requires consistent water quality with regular maintenance.
  • Adapts well to captivity when provided with a stress-free environment.

Compatibility

  • Semi-aggressive; best housed with other active but non-aggressive species.
  • Avoid keeping with highly territorial fish that may cause stress.
  • Compatible with most reef-safe species, including clownfish and tangs.
  • Can be kept singly or in a pair but may display dominance over similar wrasses.

Aquarium Behavior

  • Highly active swimmer, frequently exploring the aquarium and interacting with other fish.
  • May establish cleaning stations where larger fish allow it to remove parasites.
  • Spends time darting between rock formations and open water.
  • Becomes more confident over time in a stable, well-structured environment.
