As I have already reported in my nagyi-thread there is one single offspring which first I believed to be a young of my nagyi-pair.
But looking at the recent photos of this young – which I took to better be able to sex the fish – great doubts arose.
Being unusually colourful from the beginning the fish now reveals it’s gender clearly – but also I now mean to see a quindecim pattern in the tail fin. Something that also seemed quite unusual for nagyi to me from the beginning is the jagged seam of the dorsal and the anal fins which is deeply white. Looking at the photos of the development of my nagyi pair I found that in nagyi the teeth of the dorsal fin rays never show this deep clear white with no iridescent shimmer.
As I observed in nagyi the shimmering bands in dorsal and anal fin develop almost simultaneously. This young male in question shows a developing iridescent band in the anal fin – but not in the dorsal, which in my opinion is much too red for a nagyi.
One other feature seems to develop: at the base of dorsal and anal fin where they emerge from the body a light seam begins to show – as in quindecim. Nagyi do not show this.
And last, but not least – I mean to see a quindecim “flower-like” pattern in the tail fin …………
