Ok, so I have a panduro female, I say this because she hadn't the caudal
patch at all before the male came in and she also doesn't have  the black
patch on the gills, that should become greenish when defending a territory
or when showing aggressiveness, but she is showing only the round patch on
the body that as soon as the male came in has changed its colours to a
greenish tonality, and is always like that now.

The black marking on the caudal fin has appeared, as I said, as soon as the
male came in and it's perfectly the same as the one that the panduro male
has, so It's not really like the patch that nijsseni female has, but it's
like an irregular almost triangular big spot.

Looking at the mouth I'd really cannot say anything more. It's too
diffucult to decide, she is preatty small yet.

The male is definetly a nijsseni specimen. Well that's what I think :-)))
