Hoplolatilus marcosi - Marcos' Wrasse

Hoplolatilus marcosi (Marcos' Wrasse)

Overview

  • Found in the Western Pacific Ocean, particularly in deep reef environments with sandy substrates.
  • Recognized for its elegant elongated body, often displaying shades of light blue and pink.
  • A peaceful and elusive species, frequently seen darting into burrows when threatened.
  • Due to its shy nature, it thrives best in a well-established marine aquarium with minimal aggression.

Feeding

  • Primarily a zooplankton feeder, consuming small crustaceans and microscopic organisms in the wild.
  • Accepts a variety of prepared foods in captivity, including frozen mysis shrimp, enriched brine shrimp, and finely chopped seafood.
  • Small, frequent meals help mimic its natural feeding habits and ensure proper nutrition.
  • Supplementing with high-quality pellets or flakes can enhance overall health and coloration.

Habitat

  • Prefers deep-water reefs with soft, sandy areas where it can construct burrows.
  • Requires a tank setup with fine substrate to accommodate its natural digging behavior.
  • Best suited for aquariums with stable water conditions and moderate water flow.
  • Hiding spaces and gentle lighting can help reduce stress and encourage more natural activity.

Fish Care

  • Optimal water temperature: 74-82°F (23-28°C).
  • Ideal pH level: 8.1-8.4, with a specific gravity of 1.023-1.026.
  • Highly sensitive to water quality fluctuations; pristine conditions are necessary.
  • Best introduced into a stable, mature aquarium to minimize acclimation stress.

Compatibility

  • Extremely peaceful; ideal for community tanks with other non-aggressive species.
  • Best kept in pairs or small groups if the aquarium is large enough.
  • Avoid housing with aggressive fish that may intimidate or outcompete it for food.

Aquarium Behavior

  • Shy by nature, often retreating to burrows when startled.
  • Becomes more confident over time with a stable and calm environment.
  • Can form symbiotic relationships with other burrow-dwelling fish in the wild.
  • Requires a well-secured aquarium lid, as it is prone to jumping when frightened.
