How to sex Kribensis

[Atlantic Fish]

I have a Kribensis, and I want to get another so I can try my luck at breading them. Any idea how to sex them. I want to figure out what sex mine is so I know what to pick up at the pet store. My tank has a few other cichilds, will they still bread with other fish around?

look at them in the freshwater profiles section, it has something there about them. it has to deal with color and i think that males have longer, more pointed dorasl and anal fins

Males have a longer extension to the dorsal fin, a diamond shaped tailfin, and is a longer, sleeker fish.

The females are rounder, with a rounded tailfin. Either sex can have the red/purple tummy.
