Anyone able to sex my Electric Blue Jack Dempsey's (EBJD)?

[RossP]

Hey, Hi, Hello!
I've had these 2 EBJD since there were 1 inch or so, now 6 or 7 months later there about 4 inches and curious about their sex, is anyone able to sex them for me?

Thanks in advance.





The Larger one in top pic (at the back in the lower pic), is older and usually a lot darker almost dark purple/black, but I had to move the tank yesterday and do a substantial water change and there colours have lightened up since.


Here is my 210L Tank, I'm also looking for some interesting ideas for a backing for the tank too!

First one I would say male. Due to the pointed dorsal. But not always a definite way. Then the smaller one looks like it has a nautical hump which would lead maybe to male.

I aint a pro at sexing them though. Just my opinion.
