Red Eye Tree Frog of a VERY Different

[BArnold]

I currently have a leutino, an albino and three regulars. As well as two gray tree frogs. I was supposed to have two leutinos but one was DOA so I may save my credit for some clown tree frogs in the future. I think adding a black one would be fantastic. Does he have any currently? How would I contact him?

In nature melanism can occur in 7% of a population of certain animals. This makes them black/mainly black. There is a melanistic Gabar Goshawk (small bird of prey) that frequents my garden.. he is all black apart from white stripes on his tail. Can this occur naturally in amphibians? If albinism and leuticsm can occur naturally then its guaranteed that melanism can too. I understand that these in the discussion are bred.. but does anyone know, or heard of of any natural occurances (sorry english spelling issues again lol) of any of these mutations in any frog species? I'm rather curious
