Pseudanthias squamipinnis (Peters, 1855)
Abundant throughout the Solitary Islands Marine Park. Wide ranging throughout the tropical Indo-Pacific. In Australia recorded from Queensland south to central New South Wales and including Lord Howe Island.
Often large aggregations on edges of reefs and dropoffs. Shallow water to at least 55m.
Schools consist mostly of harems of females with one or several dominant males, as shown in top and two bottom photographs. Females, shown in second photograph, are induced to change sex by the removal of the dominant male. Usually seen feeding on zooplankton in the water column, retreating to soft corals, holes and crevices if threatened. Grows to 12cm.
