Re: Question about RBI hides
Mine went from a small when they were 17" (80 grams), now they are 24ish" (150 grams) each and uses the med. One of them still uses the small but it rest on top of his body.
I have a full grown Ball that had trouble using a large, so I went out and bout some sterilite containers, made a hole, and painted them.
Re: Question about RBI hides
I would go with the Medium hides, and just add some extra substrate or balled up paper to fill in the extra space. The smalls are really small and your snake will quickly outgrow them. The mediums will last you a while.
