Thank you, Helene.
Yes, I also have the impression that the females irritate each other. They now and then show something I would call “catfight”, you can see it on the first picture – trying to impress each other, showing off, then from time to time chasing each other.
I am slightly irritated that the male doesn’t really colour up. To me it seems quite long til he shows his colours …….. in my nagyi you could clearly distinguish the sexes after one or two days.
