Wait a minute, I just realized this was concerning a pygmy enclosure. Yeah...I have no idea about keeping that species so disregard the last post if it doesn't apply to pygmy's. hehe :o
Are you keeping a chameleon in an all glass terrarium? I'm just a newbie at this but from what I've read from the experts on this forum that's a big "no-no". All screen cage, a couple of schefflera plants, lots of vines and natural branches, proper lighting and heating and they seem to thrive...
