There are not a lot of information of Black Leopard available with a quick search. However I was able to find an article by Lemon TeaYK with a few lines on Black Leopard. In this article, there are pictures of male and female black Leopard.My back leopard is going through this transition as well. Is it just becoming an adult female or do they change genders?
The picture of Lemon TeaYK attached below.
I am not sure about this. From observing my Male Black Leopard, he switch from the suppose female to male in the picture below. He looks like the first picture when he is not excited and more like the second when he is excited.
It is possible the Lemon TeaYK is wrong.
According to Lemon TeaYK here is the female:
And here is the male:
My pictures. Male when he is not excited, and when he is in is excited:
Baseline coloration male:
Nuptial coloration male, same fish:
I will try add my male to my DT using acclimation box. Will see how the resident fish react to him in the acclimation box. Add or not depends on how they interact.
