---------------------------------------------
Description
Dorsal spines (total): 12; Dorsal soft rays (total): 12-13; Anal spines: 2; Anal soft rays: 12-13. A relatively deep-bodied yellowish-brown Chromis with a large yellow spot at the pectoral-fin base, dark outer caudal-fin rays, and elongate dorsal, anal and caudal-fin filaments. Max length: 10.0 cm. Depth range: 5 - 70 m.
Color
Light brown generally, becoming very pale to whitish below, edges of scales very obscurely darker. Iris brownish. Infraorbital gray white. Dorsals and anals deep brown terminally, last rays of soft dorsal and soft anal abruptly whitish. Caudal with upper and lower edges broadly duslcy, medianly whitish. Upper and lower edges of caudal peduncle slightly darker brown than sides. Paired fins pale brownish. Pectoral sometimes with faint brown shade or blotch basally, axil pale. Ventral dusky terminally, front edge narrowly whitish.
Etymology
Chromis: from Greek, chromis = a fish, perhaps a perch.
amboinensis: named for Ambon Island. Ambon Island is part of the Maluku Islands of Indonesia.
Original description: Heliases amboinensis Bleeker, 1871 - Type locality: Ambon Island, Molucca Islands, Indonesia.
Distribution
Indo-West Pacific: Christmas and Cocos-Keeling Islands to Micronesia, Western Australia and Queensland (Australia), New Caledonia to Yaeama Islands.
Biology
Adults inhabit coral-rich areas of clear lagoon and seaward reefs. Abundant on steep outer reef slopes below 24 m, uncommon in lagoons. Juveniles in large branching corals, adults mainly in caves. Found in aggregations. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. Feeds on zooplankton.
Similar species
Acanthochromis polyacanthus (Bleeker, 1855) - Reported from New Caledonia. The record of this species needs additional verification and the collection of specimens. This fish has a number of colour variants, and ranges from whitish to all brown or dark grey, sometimes with a white tail.

Chromis ternatensis (Bleeker, 1856) - Reported from New Caledonia - Link to the species (here).
