Thanks.I am trying to remember how big of a ball python could be before you would need to move him from the 12qt tubs to another size.I am guessing around 800+ grams(just guessing here).Tim told me the correct size and i have forgot as it was a month or so back.I can find out though and when i do i will reply with that info.Now here is a link from his home page that shows the steps for building this rack.I know you said you only have a few ball pythons,if you built a rack like this you would have the room to expand your collection lol. http://www.baileyreptiles.com/babyrack.htmlOriginally Posted by kplunk
