In Australia, males are overall steely purple with a mostly yellow head, a reticulated yellow pattern with blotches and lines on the back, a yellow dorsal fin with red anterior soft rays and a purple line between the two colours, and a purple margin. The anal fin has yellowish rays with a purple margin along the leading edge. The caudal fin has an indistinct red blotch or bar near the rear margin, with purple upper and lower margins. Females are steely purple with a yellow dorsal fin that extends onto the back to the caudal peduncle, and is separated from the purple body colour by a red arched stripe.

Longfin Basslet, Pseudanthias ventralis (Randall 1979)

More Info

Inhabits caves and coral rubble areas along steep drop-offs or channel walls.


The species is variable in colour pattern across its range, with three distinct colour morphs that are separated geographically.


The specific name is from the Latin ventralis (= of or pertaining to the belly) 'in reference to the striking prolongation of the pelvic and anal fins'.
