DISTRIBUTION/HABITAT: The Wide-Band Clownfish is found on the Western Pacific: Australia and New Caledonia inhabiting rocky and coral reefs. Depth to 5-45 metres (16-150 feet).

DIET IN THE WILD: Carnivore, feeds mainly on planktonic crustaceans (copepods, mysis, and shrimp larvae and some algae.

            Juveniles below note the different color.  NOT CURRENTLY ON EXHIBIT

REPRODUCTION: Clownfish are oviparous with distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
Protandry refers to organisms that are born male and at some point in their lifespan change sex to female. Protandrous animals include clownfish. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males will become a female. The remaining males will move up a rank in the hierarchy.

Juveniles below note the different color.  NOT CURRENTLY ON EXHIBIT

REMARKS: Associated with the anemone Heteractis crispa in the wild.
