Hi Simone, I think you have a male nijsseni but a female panduro. The colours of the male are more nijsseni, yellow/orange anal fin. A panduro male would have blue anal fin in my experience. The triangular shaped caudal marking on the female is a dead giveaway for panduro. Must say I've never seen this mark shown on a female before, but then it is not visible on all males. Keep searching, it may be worth telling your supplier assuming of course I am correct in the ID.
