Lemon Damsel

Pomacentrus moluccensis

The Lemon Damsel (Pomacentrus moluccensis) is a small Indo-Pacific reef damselfish with a bright yellow body and strong territorial behavior. It is typically seen around coral heads and branching corals, especially on sheltered reef flats and lagoons.

Identification points

Uniform lemon-yellow to yellow-orange body with no bold bars or spots
Deep, laterally compressed damselfish shape with a small mouth
Typically shows a darker eye area and may have faint bluish edging on fins in good light

Habitat

Shallow coral reefs, reef flats, and lagoonal patch reefs, usually close to branching corals and rubble; adults often stay within a small territory above live coral or near shelter.

Bait notes

Not a common angling target. If caught incidentally, small pieces of shrimp, mysis, or tiny reef fish baits may take it; very small micro-jigs or flies can also work around reef structure.

Behavior

A diurnal plankton and benthic feeder that picks tiny zooplankton and algae from the water column and reef surface. It is highly territorial, especially around coral cover, and will dart back into shelter when disturbed.

Caution

Reef fish handling can injure you with sharp coral nearby; use care to avoid cutting hands on live reef. As a small reef-associated fish, consumption is generally not a standard target and local reef-fish advisories should be checked.

Fishing notes

Best approached with ultralight tackle or small fly gear around shallow reef structure, but avoid hard fishing on live coral. Most captures are incidental rather than intentional.
