Yes, this is another 'Sex my fish' thread. I picked up two adult blue gene dempseys last night - one is a definite male and one I'm 50/50 on. Have a look see and see if anyone can tell any better than I can. The size says male, but the cheek spangling says maybe female.

Its a normal male JD
 
Male
 
Definately male. Blue gene means it carries the Blue gene but doesn't exhibit the trait, thus sexing should be the same as a normal JD. Female JDs typically have blue ONLY on the gill cover and a relatively plain rest of the body. Males have color covering the body and can have a little or a lot of color on the gill cover. It all depends on the individual fish. Here is a pic of my male and female so you have a reference, if it helps.
