The Blackmargined Damsel, Pomacentrus nigromarginatus, was regularly collected in stations of 20m or greater in depth. It is easily recognised by the grey background colour with darker scale margins; by the dark border on the caudal (tail) fin; and by the large black spot on the pectoral fin base.
The 7cm long Blackmargined Damsel in the image was collected in the Reef Islands Group, Solomon Islands.
