I just read an article today by J. Vierke – you can see it here http://www.fischreisen.de/Parosphromenus_nagyi.html
One of the photoes is actually also part of our species describtion of P. nagyi.
If you look at the last photo in the article, does the fish not show actually the same as you are describing (at least in terms of the iridiscent that you see), Stefanie ?
