size of 6-8cm, found within 7-8m coral reef area. Certainly from Family Pomacentridae
Black spot in the pectoral fin, yellow margin at the dorsal spine, with black spot or probably an ocellus at the anal fin, and has bluish ring in its eye
I have looked in references such as Damselfishes of the World (Allen 1991), World atlas of marine fishes (Kuiter and Debelius, 2006), Reef fish Identification (Allen et al 2003), and Indonesian Reef Fishes (Kuiter and Tonozuka, 2011), however, I still can't find an exact match.
Thanks

Good luck
Difficult to say, as the image is somewhat blurred. The fish looks similar to Chromis margaritifer, but could be another, closely related species. Do you have any other images where you can see the caudal fin and count lateral-line scales?
Thanks for the responses. Here is another picture I have, this is more blurry but you can see the caudal fin of the fish (lower right). The tail is more lobed, so i'm leaning towards Pomacentrus or Stegastes. Unfortunately, I don't have a voucher specimen to do meristics, but I would probably do it when I have the opportunity to go back to the site. Is it possible that this fish may be a colour morph of Stegastes partitus?, although, Stegastes partitus has never been recorded in the Philippines. Thanks
The caudal fin shape rules out the Chromis hypothesis, and rather points towards Pomacentrus.
I don't think Stegastes partitus is an option; the colouration of that Western Atlantic species is quite different, for instance that species wouldn't have the black blotch on the pectoral-fin base.
Maybe it is an unusual colour morph of Pomacentrus philippinus, or a species in the complex similar to Pomacentrus nigromanus and P. nigromarginatus; see the photographs in Allen & Erdmann (2012: 621-621). I doubt a positive identification without specimens would be possible in this case.
