How do you sex Kribs?

IME, Kribs are quite unusual inasmuch as the females are very intolerant of each other.
 
WOw,

I have been considering getting into this breed for a while. A LFS has some "wild caught" kribs that are about 3 inches long. Is that a good solid adult size for wild caughts? I've honestly never seen any larger in captivity.
 
Ive never seen any kribs at a store that was over 2 inches in size. Mine are just a tad over an inch. Yeah I think 3 inches would be a good size becasue they would most likly have already matured. But I would be careful in buying ones that are said to be wild caught. I read on a site that kribs sold in stores as wild caught are normally some other type of dwarf cichlid.
