Onespot Demoiselle
Chrysiptera unimaculata
Onespot Demoiselle is a small, reef-associated damselfish from the tropical Indo-Pacific, recognized by the single dark spot near the upper base of the tail. It is mainly of interest to aquarists rather than anglers, and reliable species-specific fishing information is limited.
Identification points
- Single dark spot at the upper rear of the body near the tail base
- Bright blue to blue-green body typical of Chrysiptera damselfishes
- Compact oval body with a continuous dorsal fin and small mouth
Habitat
Shallow coral and rocky reef slopes, rubble zones, and lagoons; usually close to branching corals or sheltering structure in clear tropical marine water.
Bait notes
Not a common sport or food fish. If encountered while reef fishing, tiny pieces of shrimp, mysid-sized natural bait, or very small plankton-style flies may elicit strikes, but it is generally not targeted.
Behavior
A territorial, diurnal planktivore that stays near cover, often in small groups or loose aggregations. It forages in the water column above the reef and darts back into shelter when threatened.
Caution
May contain reef-associated ciguatera risk depending on locality; not generally eaten. Handle carefully to avoid stress and injury to the fish, and check local rules because ornamental reef species may be protected or collection-restricted.
Fishing notes
Best observed rather than pursued; if collecting is legal, use very light tackle or small hand nets only where permitted. Avoid damaging coral or chasing fish into the reef structure.
