JD Sexing? And 2 Others(africans?)

[SuddenUrge]

Just took over ownership of a 55 Gal. tank. Has a what I know for sure is a Jack Dempsey but I can't tell the sex of it. Also Tank came with too smaller electric yellow labs but I can't tell if they're male of female yet
Anyhelp would rock!
Thanks in Advance!

I'll copy this to the African ID forum for you, but I don't believe yellow labs show sexual dimorphism.

The JD looks male to me.

Thanks Mac, I'm sure its been mentioned in another thread but what exactly are the tell-tail signs of which gender(heh bad pun...sorry its late) ?
