Congratulations on your pygmy colony.
We have only had ours a little over a year now, so we're not real experienced. But here are a few observations:
Our colony developed an Alpha male, AND what appeared to be an Alpha female. The Alpha male would show his colors and patterns, while the subordinate male remained dark. We also observed the alpha male attack the subordinate male once. We had to separate our colony. I don't think this always happens. We thought we'd be safe, because we have a very large 50 gallon tank. We placed a separator in it so each half of the colony could have their own side and not see the others.
The Alpha female would mate and produce eggs. The other female did not.
We dug up the eggs, when we could find them. She laid one clutch we did not find, and one day, lo and behold, there was a brand new baby in the shrubs. Unfortunately, his legs are not right. They look like they are on backwards or something, and he does not use them. He lives separately, in a tub with paper towels and a fake plant branch. He crawls around on the towels and drinks water from the plastic leaves and eats the tiny crickets I put in there. He poops regularly. He is about 6 weeks old. SO, we recommend digging up the eggs, as then you can control the moisture and temps better for the developing fetus. I think his egg was laid somewhere in the tank where the conditions were not quite right.
Also, I don't recommend combining beardeds with temporalis. We had to separate ours when the temporalis tried, and almost succeeded, to mate with a bearded girl.
If you keep your soil too moist you may end up with a fungus gnat infestation.
We really enjoy having our little pygmies. They are worth keeping, and really very little trouble.
