Pseudanthias bartlettorum
A small anthias with a lavender body and yellow back and fins, native to the central Pacific around Palau and the Marshall Islands. Hardy and well suited to group keeping; small feedings several times a day are the basics.
Bartlett's anthias (Pseudanthias bartlettorum) is a small anthiadine of the central Pacific, known from Palau, Kosrae in the Caroline Islands, Kwajalein in the Marshall Islands, Nauru and Fanning Island in Kiribati, with a recent record from Tonga. On coral reefs at 4-30 m it forms large aggregations of a few males with several dozen females and juveniles. The body is pale lavender, with bright yellow from the back across the dorsal fin to the tail. Maximum length is about 9 cm. It is a protogynous hermaphrodite: when the male is lost, the largest female changes sex. It is regarded as one of the hardier, easier anthias and suits reef aquaria. As a planktivore it should be fed frozen mysis, enriched brine shrimp and similar foods in small amounts several times a day; a refugium supplying copepods adds stability. Keep one male with several females in a tank with brisk flow and rockwork for shelter. Because there is some squabbling within the species, introduce the whole group at once.
