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.

I believe this guy to be just that a male electric blue gene maybe?

well as much as id like to be able to tell you my female (i assume shes a female) JD has paired up with one of my other 3 i cant. aggression levels in the tank are starting to rise as i watch everyone take turn at lip locking to prove who's the boss of my tank, 3 of the four of my Jack Dempsey's...

hey guess so i have 4 jack dempseys in my tank, i got these fish from a dealer close to me and im not sure on there age, hiow long do you think til they will pair up? im not sure the sex of three. one i can tell is a female the others i think are to young to tell, these pictures kinda suck so...

So I finally finished my 180 gal project tank some weeks back. And just stocked it with some new world cichlids black convict, green terror, bleekeri and some misc also , I got 3, 3" long Jack Dempsey's that supposedly have the blue gene. Im hoping for a mating pair but I'm not sure on the sex...
