By the way there is an unrelated female in the tank as well who is terrified of this one and hides 24-7 from this one. Shes about 6" and has a more blond colr to her but all the markings are the same on both.
 
Try putting a mirror next to the tank and see what colour he or she goes.. Umbee can be difficult to sex. Are you 100% sure the small ones female.

I'll try the mirror thing when I get home today, what should I be looking for that would suggest male? Also the small female is a proven female, from a hobbyist here in Seattle who produced her.
 
So the colors wash out and the head goes dark when a mirror is put up. Pretty much the same thing that happens when the smaller female comes out. Head shaking tail slapping etc...
