Palau and Marshall Islands in Micronesia. Morphology: Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9. Uniformly lemon yellow except for a pale area on the cheek. Biology: Lives among staghorn Acropora corals in lagoons and hovers among or above the branches and also rests on them. Occurs in aggregations of 5-15 individuals Aquarium Care: Has a temperature range of 68 - 77°F (20 - 25°C) and natural diet consists mainly of zooplankton. Requires a meaty diet, i.e., enriched brine shrimp, mysis, finely chopped fish or shrimp flesh, and other various frozen carnivore foods, with one or two feedings per day. They should not be housed with aggressive fishes such as groupers, dottybacks, triggerfishes or aggressive angelfishes. In a reef tank with sps corals, feeding can be reduced to once every other day. Extremely popular, yet their normal life span is extremely short compared to other marine fishes, usually about one to two years. Captive bred specimens available.
