Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Western Pacific: Peninsular Malaysia to Hong Kong and the Ryukyu Islands, south to Western Australia, and east to Vanuatu and the Gilbert Islands. Replaced by an undescribed species at Fiji and Tonga and Pseudochromis coccinicauda in the Indian Ocean (Ref. 37816).
