Overview

  • Native to the Indo-Pacific region, commonly found in shallow reef environments.
  • Recognized for its slender body with striking orange and blue horizontal stripes.
  • A peaceful species known for its algae-grazing and sand-sifting behavior.
  • Popular among marine aquarists for its beneficial role in controlling algae and detritus.

Feeding

  • Omnivorous diet, primarily consuming filamentous algae, detritus, and small invertebrates.
  • 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 grazing.
  • Requires an aquarium with live rock and fine sand for natural foraging behavior.
  • Thrives in environments that allow it to exhibit its natural algae-eating 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.
  • Can be shy when first introduced but gradually becomes more confident.
  • Providing a peaceful environment with minimal aggression ensures longevity.

Compatibility

  • Peaceful and best suited for community reef aquariums.
  • Compatible with other non-aggressive fish such as clownfish, wrasses, and gobies.
  • 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, grazing on algae and sifting through sand.
  • Helps control algae growth, making it a beneficial addition to reef aquariums.
  • Can be timid but becomes more active once comfortable in its environment.
  • Providing a well-structured tank with live rock encourages natural foraging behavior.
