I house all my young ball pythons (from approximately 90g to 800g) in 30-31 qt IRIS tubs as their "grow up" enclosures prior to moving them into a final, larger enclosure. Occasionally I will have to add additional clutter for the smaller snakes, but overall, I have had very few issues with this approach.
thank you for the reply! that makes me feel better about the switch. i think after she sheds out i'll move her!
