Aren't you worried about the snakes burning themselves on either the bulbs or the dome fixtures hanging inside the enclosure? It looks like an accident waiting to happen to me.
It looks dangerous, I agree, but it ain't . The dome's get a bit warmer than 90 degrees but they are comfortable to hold. I can hold them without getting burned. The CHE is surrounded with a metal wire cage, so are the undersides of the domes. So I'm not that worried.
