Overview

  • Native to the Indo-Pacific region, commonly found in coral reefs, lagoons, and seagrass beds.
  • Recognized for its white body with bold black stripes, yellow fins, and distinctive blue markings near the eyes.
  • A small but bold species known for its inquisitive nature and playful swimming behavior.
  • Possesses the ability to inflate its body when threatened as a defense mechanism.
  • Requires a well-maintained aquarium with plenty of swimming space and rock formations for exploration.

Feeding

  • Omnivorous, feeding on algae, small crustaceans, and invertebrates in the wild.
  • Readily accepts frozen shrimp, mysis shrimp, marine pellets, and finely chopped seafood.
  • Requires hard-shelled foods such as snails or clams to naturally wear down its continuously growing teeth.
  • Multiple small feedings per day ensure optimal health and prevent malnutrition.
  • A varied diet helps maintain bright coloration and supports overall vitality.

Habitat

  • Commonly found in shallow reef environments with sandy bottoms and coral rubble.
  • Prefers stable water conditions with moderate water movement.
  • Aquarium setups should include live rock formations, caves, and sandy substrate for natural foraging.
  • Thrives in well-maintained marine tanks with a diverse and balanced environment.
  • Providing adequate hiding spaces helps reduce stress and encourages natural behaviors.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C) to support a strong immune system.
  • Preferred pH range: 8.1–8.4, with a salinity level of 1.025–1.026 (about 33–35 ppt).
  • Requires efficient filtration and regular water changes to maintain high water quality.
  • Should be housed in a peaceful tank environment to prevent stress.
  • Providing an enriched habitat and a varied diet promotes longevity and well-being.

Compatibility

  • Generally peaceful but may nip at slow-moving fish with long fins.
  • Compatible with tangs, wrasses, and other semi-aggressive fish.
  • Not reef-safe, as it may prey on small invertebrates such as shrimp and crabs.
  • Should not be housed with overly aggressive fish that may cause stress or outcompete it for food.
  • Providing enough space and a well-structured environment helps minimize territorial disputes.

Aquarium Behavior

  • A curious and active species that enjoys exploring its surroundings.
  • Frequently seen picking at rock surfaces and investigating objects in the tank.
  • Capable of inflating its body when startled, though this behavior should not be intentionally provoked.
  • Providing rock formations and varied tank decor encourages natural foraging behavior.
  • Over time, it can recognize caretakers and display interactive behaviors during feeding.
