Origin
Native to the Western Atlantic, especially the Caribbean Sea and Gulf of Mexico. Often found in coral reefs, rocky crevices, and shallow rubble zones.

Visual & Functional Appeal
Displays a striking pattern of neon blue and white vertical stripes along its slender body. Remains small (1.5–2 inches) and spends much of its time perched on rocks or substrate.

Purpose
Functions as a cleaner fish—removing parasites from tankmates—and as a lively visual addition to nano and reef aquariums. Also helps control microfauna populations.

Importance
Perfect for nano tanks, beginners, and peaceful reef setups. Its utility as a cleaner and small size make it a great fit for crowded or intricate aquascapes.

Included Resources
Needs mature live rock, moderate flow, and high water quality. Prefers tanks with multiple hiding places and open areas for perching.

Best Use Cases
Nano reefs, peaceful community tanks, coral-focused aquariums, and mixed-species displays. Ideal for tanks under 20 gallons.

Conservation Context
Extensively bred in captivity, drastically reducing the need for wild collection and supporting ethical marine aquarium practices.
