Free range or pygmy fit the specialized enclosure tyoes. the rest of the forum category is for the regulars most people here have. Pygmies should be kept bioactive, usually glass, all natural enclosures. Free range is for keeping chameleons outside of an enclosure while still providing uvb, humidity, misting, basking, etc.
That is why there are two small forums for them.
Edit: free range could apply to any species...
