I was just surfing random snake sites, and came across this rescue group in Colorado... they had a list of recommended enclosure sizes, and I was quite surprised at their suggestions! http://www.corhs.org/habitat.html

55 gallons minimum for a BP? And an entire room for an iguana? My (baby) BPs are in 10/15 gallon tanks, and they seem to be doing fine... when they're bigger, I was planning to upgrade to 20-30 gallons. Isn't that what is usually recommended? Just wanted to make sure I wasn't delusional, LOL.
