Its hard to say, – I wouldnt be able to, – but its a very interesting fish, nice to see that it actually is maybe ‘close’ to what they say it should be.
Have you ruled out opallios ?
If you look at the image at http://www.igl-home.de/bilder/gallery/parosphromenus/00.pOpallios.KOS.male.800×600.072dpi075.html I would think theres also quite some similarities.
But the likeness to phoenicurus is big too.
