On some level I really love species diversity, but it's led me to having a lot of 'singles' without partners for future breeding. I don't really want to breed everything anyway, so it's not that much of a problem. I find that it's pretty easy to keep some leopard geckos, hognose, and the ball pythons in the same area since they have fairly similar warm ambient temp requirements. I don't have too much of a problem with keeping the ball pythons at a higher humidity than the others since they're in a rack on cypress mulch.
