Talbot's Damselfish

Talbot's Damselfish is a small reef fish in the genus Chrysiptera, found across parts of the western Pacific, including areas of Papua New Guinea, the Solomon Islands, and neighboring waters. It is distinguished from related Chrysiptera species by its yellow head and nape set against a pale lavender-grey body, together with a prominent black spot on the rear part of the dorsal fin. Like other members of its genus, it favors shallow, sheltered reef habitats with abundant branching coral, where it lives in small groups closely tied to a home coral colony.

Key features for identifying Talbot's Damselfish:

• Bright yellow head and nape
• Pale lavender-grey to bluish-grey body
• A distinct black blotch on the rear (soft) portion of the dorsal fin
• Small, deep, laterally compressed body shape, typically 5-6 cm
• Rounded caudal fin and moderate dorsal fin height, with a close association with branching coral shelter The combination of a yellow head, a grey body, and the black rear-dorsal-fin spot is the most reliable way to separate this species from related blue-and-yellow Chrysiptera damsels.

Talbot's Damselfish is found on coral reefs in parts of the western Pacific, including areas around Papua New Guinea, the Solomon Islands, and nearby island groups. It typically inhabits shallow reef flats and lagoon environments at depths of 1 to 12 meters, sheltering among live branching coral colonies such as Acropora. It favors warm, stable tropical waters generally between 24 and 29°C and rarely strays far from its home coral structure.

Talbot's Damselfish lives in small, loosely social groups centered on a single coral colony, following the typical Chrysiptera pattern of a dominant male overlapping territory with several females. It feeds on a combination of planktonic prey taken from the water column and algae grazed from coral and rock surfaces. Individuals are moderately territorial, chasing off similarly sized intruders that approach their home coral, while retreating into the coral branches when larger predators appear. Breeding involves courtship displays by the male followed by the female laying demersal eggs on cleared substrate, which the male then guards and fans until hatching. Its close ties to live coral make it sensitive to local reef condition.
