Species Name: Premnas biaculeatus

Authority: (Bloch, 1790)

Common Name: Maroon/Spinecheek Anemonefish

Range: Widespread in the West Pacific and East Indian Oceans

Size: Female - 6.5 inches - 16 cm, Male – 3 inches – 8 cm

Natural Environment: Inhabit protected coastal waters and lagoons

General Husbandry: Has a temperature range of 77 - 82°F (25 - 27°C), and accepts a wide variety of foodstuffs, e.g. mysis shrimp, fortified brine shrimp, various meaty diced fish and shrimp flesh, and Spirulina flake. Should be fed a few times per day. Largest and most aggressive of anemonefishes and should either be kept singly or in mated pairs. Quite aggressive towards other anemonefishes. Captive-bred specimens are available. There appears to be two Maroon Anemonefish/Clownfish strains, a yellow-striped, and a white-striped version. The yellow-striped version hails Sumatra, and may simply be a geographical variation with a more deep red/chocolate brown color with wide yellow stripes. The brilliant red/orange version has thin white stripes. It is reported (Wilkerson, 1998) that the white striped variety is more aggressive. Host anemone in the aquarium appears to be only: Entacmaea quadricolor.

Aquarium Suitability: Extremely hardy, but probably the most aggressive of anemonefishes. A good beginners fish, and well suited for most aquarium styles. But do not keep with timid tankmates.

Note: Captive bred species - generally widely available
