N W Solitary Island
Common name: Dick's Damsel

Uncommon in the Solitary Islands Marine Park. Found throughout the Indo-Pacific: East Africa to the Line and Tuamoto islands, north to Japan, south to Australia. In Australia recorded from Geraldton in Western Australia to the southern Timor Sea, from north Queensland south to northern New South Wales and including Lord Howe and Norfolk Islands.

Ecological Notes:

Found in clear water around offshore islands and coastal reefs. Frequently associated with Pocillopora or Acropora corals. Depth range to around 15m.

Additional Notes:

This species feeds on filamentous algae and small benthic invertebrates. Wary and difficult to approach, readily retreating to cover. Males and females pair during breeding, the resulting eggs are demersal and attached to the substrate where they are aerated and guarded by the male. Similar to and sometimes confused with the Johnston Damsel Plectroglyphidodon johnstonianus which is similar in colouration and body shape but has a yellow tail. Grows to 11cm.
