Ted,,,I just tried to find images on Google of ther Fronts sex organs with no luck. (sounds sick huh). Melafix fix!
But I read up on some things and it is said that both the male and female
will indeed grow the hump,,but the males will be more difined. And the older the fish, the larger the hump.
I've got a few of Les' Front pic on my comp. I will check to see if I have shots with the difference and post. I dont think I need his permission as long as it's helping someone. idunno
Heres one,,,I know he's got more,,,but he's not on right now.
Female on left and male on right. (I hope) idunno
The male,,,I think is the sub-dom one.

And the dom one. idunno
