Sometimes you need male to male interaction to get them wanting to court females. However, I would first start by just letting them see each other by putting the two enclosures together and hope that worked. If not and I wanted to get some breeding action going I would house two males in a large cage with the RECEPTIVE female in there. This will sometimes trigger natural responses that some captive chams have "lost". I housed all my K. tenuis together (2.2) in hopes that the males would fight and then...........breed

They were pissed for a week and displayed at each other but in the end they never did breed with the females and got accustomed to each other and would actually sleep side by side


Whether or not this is a case of just wanting them to fight or trying to trigger them to breed is questionable but he did say fight over a female. I wouldnt jump to conclusions so fast.
