Damsel fish id

Possibly Spiny Chromis (Acanthochromis polyacanthus) but photo quality makes it a bit tough to say for sure.

Thanks!

I doubt this is Acanthochromis polyacanthus. A. polyacanthus has a white tail, and the head shape is different.

EDIT: It seems A. polyacanthus has different colour morphs, not all with a white tail (that's the morph I'm most familiar with). Still, the head shape looks wrong to me, but I'm no expert on damselfish ID.
