I have to Yemen Chameleons. That are housed together in a 100 Gal Flexarium. They are both around 8 months old not related. They have got on fine together but a few minutes ago i saw the male grab the female and they looked like they were about to fall as the female was getting herself in a state and i noticed that the male was mating her. Now they werent "connected" for very long. How long does it take the male to pass the sperm? We were planning on breeding them so if she does become gravid we arent to concerned as we have plenty of spare flexariums and time and money for them.
