How To Sex Bolivian Rams

[UKSPEED]

I've recently bought 2 Bolivian Rams. Can anyone tell me how to sex them?

They seem to be bashing into each other quite a bit, and almost lip locking. I don't know if this is a sign of 2 males/females, or a sign of dominance before pairing up.

Thanks.

Barry White, scented candles but probably best to leave out the bubble bath

^^^^BAHAHAHA too good! I believe males are larger and more colorful but you could probably find more help in the new world/south American cichlid section
