Princess Damsel

Pomacentrus vaiuli

Princess Damsel (Pomacentrus vaiuli) is a small Indo-Pacific damselfish of coral reefs and lagoon rubble, often seen in pairs or small groups near shelter. It is not a major target fish, but it is common in reef aquariums and on shallow reef margins.

Identification points

Small damselfish with a compact oval body and relatively small mouth
Usually pale blue to bluish-gray with a yellowish to orange tint on the body or fins depending on age and locality
Frequently stays just above branching coral or rubble and retreats quickly into shelter

Habitat

Shallow coral reefs, reef flats, lagoon edges, and rubble zones with branching corals or rock crevices; usually close to cover in clear tropical saltwater.

Bait notes

Not a typical angling target due to small size. If caught incidentally, tiny pieces of shrimp, squid, or fish flesh, or small reef flies/micro-jigs, are the most plausible offerings.

Behavior

Diurnal and territorial around its shelter, picking small plankton, algae, and benthic tidbits from the water column and reef surface. Juveniles and adults stay close to structure and dart back into cover when disturbed.

Caution

Handle gently and avoid damaging coral habitat; some regions regulate reef collection and live-capture fisheries. Spines are not a major hazard, but reef cuts and punctures are a risk around coral.

Fishing notes

No specialized sport fishery; most encounters are by reef netting, aquarium collection, or incidental catch. Use very small hooks and light tackle near coral structure if targeting similarly sized reef fish.
