These fish were in the process of mating. The male was darting about and displaying. The female stayed on the bottom and 'wiggled'. The male darted over and quickly covered the female. The cloudy area over the left side of the male's head is probably released sperm.

Hi Graham,  Please see my reply to your post on the factsheet for the species.

All of my reference books, and the Australian Museum website, show that the distribution of the fish Ring-scale Triplefin (Enneapterygius atrogulare) is along the East coast of Australia. I think I have identified it in Cockburn Sound, Western Australia. Please could you check the identification of the fish in the attached image taken on 28 Feb 2010 at a depth of 3m~5m (I've had to drop the resolution to 72dpi in order to upload it). Assuming it is the Ring-scale Triplefin, do you know of any other reported sightings from Western Australia?
