Overview

  • Native to the Indo-Pacific region, commonly found in sandy and rubble reef environments.
  • Recognized for its elongated body with brown and white horizontal bands.
  • A peaceful species known for its sand-sifting behavior, helping to keep the substrate clean.
  • Popular among marine aquarists for its ability to reduce detritus buildup in aquariums.

Feeding

  • Readily accepts frozen and live foods such as mysis shrimp, brine shrimp, and copepods.
  • Can be trained to eat high-quality marine pellets and flakes.
  • Multiple small feedings per day help sustain their energy levels and health.

Habitat

  • Commonly found in sandy-bottom reef environments with moderate water flow.
  • Prefers stable water conditions and ample open space for burrowing and sifting sand.
  • Requires an aquarium with fine sand substrate and rock structures for shelter.
  • Thrives in environments that allow it to exhibit natural sand-sifting behavior.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C).
  • Ideal pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
  • Requires a well-maintained tank with stable water conditions and adequate filtration.

Compatibility

  • Should not be housed with large or aggressive species that may intimidate them.
  • Often does well when kept singly or in mated pairs.

Aquarium Behavior

  • Spends most of its time near the substrate, sifting through sand for food.
  • Helps keep the sand bed clean by removing detritus and uneaten food.
  • Can be timid but becomes more active once comfortable in its environment.
  • Providing a well-structured tank with soft sand encourages natural digging behavior.
