Description

The saddle anemonefish is a reef fish from the eastern Indian Ocean, known from the Andaman and Nicobar Islands, Thailand, Malaysia and parts of Indonesia. It grows to about 14 cm and is bright orange-red with a large black saddle blotch on the rear flank; juveniles sometimes also have a white head bar that later disappears. The fish lives in symbiosis with sea anemones in shallow, sheltered coastal waters and is usually found in pairs. Like all anemonefish it is a protandrous hermaphrodite: individuals start as males and the dominant fish changes into a female. The males guard the eggs. The species can live to sixteen years and is assessed as Least Concern (LC).
