Sexing Kribs?

[Tyrotoxism]

I recently brought two kribs. Not really intended as a breeding pair, but I can't determine 100% what genders I got, I think there is a male and a female, but the one I think is female is really nasty, so it could possibly be a male.
These are the two fish;

Any help is appreciated

100% two males

Okay, thank you. Do you think I should get rid of one of them? Maybe get some female ones so he doesn't get lonely? Or will they sort themselves out? I think one of them has claimed the entire bottom of the tank, which leaves the other hiding near the top of some of my taller plants, so one will probably be re-homed

Both males.
Females have a more rounded belly.

I would see if your lfs would just swap one of the males for a female as it is there mistake in the first place. And i would get two females and let the male pick which one he wants. Add a few terracotta pots for them to breed in. And check out my kribensis breding journal.
