Origin
Found throughout the Indo-Pacific, especially in coral reefs of Indonesia, the Philippines, and northern Australia.

Visual & Functional Appeal
Electric blue body with black “palette” pattern and a bright yellow tail. Moves in swift darting motions, bringing energy to the midwater column. Excellent schooling behavior if kept in groups.

Purpose
Serves as an efficient grazer of algae film and detritus. Enhances reef tanks with motion and color. Can reduce algae buildup in rock crevices and shadowed areas.

Importance
An engaging and peaceful reef inhabitant that adds visual brightness and maintains ecosystem balance through its herbivory.

Included Resources
Requires strong current, high oxygen, and UV-sterilized systems to reduce disease. Live rock provides grazing zones and shelter.

Best Use Cases
Active community reef tanks, Indo-Pacific biotopes, or as a focal fish in coral-heavy aquascapes. Can be kept in groups with large tanks.

Conservation Context
Populations are under collection pressure in some regions. Captive-bred specimens are increasingly available and encouraged for sustainability.
