Be patient man. First, you have to make sure you got a male and a female. Second, have the proper setup(cocohuts with petri dishes under them and lots of them), leaf litter is always a great idea, keep the light cycle at about 12 on and 12 off, mist heavily, feed heavily, use a good supplement, clean water, and leave them alone. Some of my groups have taken up to a year and a half to do anything while others have got it going on after about 6 months or so old. Just be patient and look for breeding behavior.I always like to open the window when it rains out too.
