May I repeat my question from post 1474 in this thread?
Today again I recognized that the lower half of the horizontally divided body colouration of the male is not black, as described. It seems to be black when not illuminated in the right angle – but it is as iridiscent as the pectoral fins actually.
You can suggestively see this on the last three pictures in post 1480.
Here are two more photos, not quite sharp – but you can see well enough what I mean:
I haven’t seen this on any of the nagyi-pictures I have seen yet – and I didn’t find it mentioned in any of the descriptions I’ve read.
Is this a feature only of the form from Pekan Nenasi – or do all nagyi-males show this?
