In this photo, many of the traits that are common within the local population of Regal Demoiselle (Neopomacentrus Cyanomos) are clearly visible, namely:

The orange-coloured "ear-spot"
The neon blue fin margins
The white mark at the rear of the dorsal fin
The pale, blotchy markings which may be related to nesting activity

Regal Damselfish (Neopomacentrus Cyanomos)

Regal Demoiselle (Neopomacentrus Cyanomos) can often be found darting in and out of disused oyster shell, which they use for protection and also as a safe place to lay their eggs, as the individual in this photograph was doing at the time (the eggs are the tiny brownish dots inside the shell).
