Ok in a month I purchased my first two ball pythons and now am looking to get another two within the next 2 weeks. I am building another rack (larger) and was wondering what size tub everyone uses for what size snake? In other words below are the tubs I am looking to get all IRIS. If you all would be kind enough to copy the sizing and let me know what is the maximum weight ball you would put in there. I found one very dated thread as in I think 6 years with a large variance as to what was acceptable. If there's enough of a response I will try and average them all and update this first post. Thanks in advance!

13.63 x 8.13 x 4.38 (6 qt.)

16.14 x 10.62 x 5.90 (13.5qt)

24.21 x 16.14 x 6.29 (33 qt)

33.5 x 17.8 x 6.0 (37 qt)
