And after seeing your following post, I see you have stated your alternate perspectives - thank you! And thanks for the pics!

Just for the record, I have no problem with glass enclosures. My snakes are all currently in tanks and they are all doing great! My issues were more with regard to size: the size tank standing on end that the OP first talked about is quite narrow and my concern was for the sideways thermal gradient. I only suggested the pvc cages as a matter of convenience - not that glass and screen was bad. It most certainly is not necessarily so.

No, chondros can't read, lol. But the advice given in that book is deamed from Greg's 30 years experience working with them. I still say my original advice was in no way "misleading". Sure, there are other ways of doing things and those ways are not necessarily wrong. But a recommended way is recommended by experts for a reason: it works and provides more convenience and ease of care which is helpful to a newbie.

Incidentally, I have read that paper by D. Wilson and it is a good read.
