Labroides dimidiatus - Cleaner Wrasse

Labroides dimidiatus (Cleaner Wrasse)

Overview

  • Widely distributed across the Indo-Pacific, often found in coral reefs and coastal lagoons.
  • Easily recognized by its sleek, elongated body and distinct black stripe running from head to tail.
  • Plays a vital role in reef ecosystems by removing parasites from larger fish.
  • Forms cleaning stations where fish line up to receive its services.

Feeding

  • Primarily feeds on parasites, mucus, and dead skin removed from host fish.
  • In captivity, may struggle to adapt to artificial diets but can accept finely chopped seafood, brine shrimp, and plankton-based foods.
  • Encouraging feeding with frequent small meals helps maintain health.
  • Best housed in aquariums with active fish willing to accept its cleaning behavior.

Habitat

  • Inhabits coral reefs with rocky outcrops and ledges where it can establish cleaning stations.
  • Requires an aquarium with open swimming space and moderate water flow.
  • Best suited for large, well-established reef tanks with a stable fish population.
  • Avoids high-intensity lighting and benefits from shaded areas in the aquarium.

Fish Care

  • Optimal water temperature: 76-82°F (24-28°C).
  • pH level: 8.1-8.4, with a specific gravity of 1.023-1.026.
  • Highly sensitive to poor water quality; requires pristine conditions and regular maintenance.
  • Best kept by experienced aquarists due to its delicate nature and dietary needs.

Compatibility

  • Generally peaceful but can become aggressive toward similar-looking species.
  • Best housed with reef-safe fish that tolerate its cleaning behavior.
  • May not thrive in tanks with aggressive predators that do not recognize it as a cleaner.
  • Should not be kept in small or sparsely stocked tanks, as it relies on fish interactions.

Aquarium Behavior

  • Highly active and constantly on the move, seeking out fish to clean.
  • Forms social bonds with larger species, reducing their stress levels through cleaning interactions.
  • Exhibits a unique swimming pattern, darting quickly between host fish.
  • Requires a stable tank environment to prevent stress-related health issues.
