I am just wondering. A lot of people so NO to vivariums but yes to keeping baby Leopards in rubber maid containers. Why is that? Both would hold humidity? I have a 40 gal. Breeder tank that I was thinking of covering the bottom ( so the tortiose could not see out ) and putting some type of plexiglass at the top to hold the humidity it. Can anyone shed some light on why one method is better then the other? Thank you
