Hey other MFK,
These are my 2 jack dempsey I have. I think I have a Male, Female pair but I'm not 100 percent. I know for sure I have 1 female the larger of the 2.
Awsome. Thank you. I believe the lighter jack is a female as well, I mainly was questioning the darker one. Iv had both of them sense they were half inch. I got both of them and different times months apart.
Black is a male because there is absolutely no blue by the mouth. Females have a lot while males have less
My male:
I remember reading that head profile is also different between the two.
Thanks! I’m very impressed with him, considering he was a half inch runt at a petsmart.
Jacks will breed pretty easily, they should start pairing soon.
Happy to help!
