That is a NICE male. It is kind of weird to hear you looking for a Female Banded. I have just the opposite as you do. I have a Male Banded and a Female striped that I am hoping on breeding this year. Where are you located? I am in Southern California..
Heres my Male


Here is my Female.


and here is my Second female I plan on trying to breed with the male also to see what I get.


Good luck with finding your female..
