Since space is an issue for me and I'd like to get something different from a BP (though still thinking of investing the money into my BP projects, still getting information on my options) I'd need a snake that could be kept in a CB70 tub (I have a 7030 from ARS and really have no more room for cages, except maybe one of those custom aboreal ones from boaphile or vision I think, heard it recommended somewhere but I can't seem to find the exact cage) and be happy and healthy.

I was told that carpets could be and would just use their hide as a makeshift perch and just be fine. Is that right? What about crosses like 50/50 or 75%s?

If a CB70 wouldn't work would a 36L x 20W x 14H work for an adult?

Thanks.
