Amphiprion biaculeatus
The largest anemonefish, with a deep red to maroon body, three white bars and a pair of spines on each cheek. Females reach 17 cm and are far larger than males. Extremely aggressive; it cannot share a tank with any clownfish other than its own mate.
The Maroon Clownfish (Amphiprion biaculeatus) is found in the Indo-West Pacific from India through Indonesia, the Philippines, New Guinea, the Solomon Islands and Vanuatu to northern Queensland. Long treated as the sole species of the genus Premnas, it is now placed in Amphiprion by both WoRMS and FishBase. It lives in sheltered coastal waters and lagoons at 1-16 m, mainly with the bubble-tip anemone (Entacmaea quadricolor). The deep red to maroon body carries three white bars (yellow in Sumatran fish) and a pair of cheek spines that give the species its name. It is the largest anemonefish, reaching 17 cm with a common length around 13 cm, and females are much larger than their mates. It feeds on zooplankton and benthic algae, spawns in pairs on the substrate, and the male guards the eggs. It is bred extensively in captivity and designer strains such as Lightning and Gold Nugget are traded. It is hardy and easy to keep but the most aggressive of all clownfish, attacking other clownfish and peaceful fish. Keep a single pair in a tank of 114 L or more with only robust tank mates.
