Thank you to all who responded! I greatly appreciate it.

The consensus about the enclosure size seems to be a bit mixed. I am pretty attached to a BCI/python (thank you for all the other python options!), so I have to ask, if the problem is primarily heat/humidity, would a tote just... be better? I have listed my reservations about them, but after doing some cruising around the threads here, I think I could make one that would satisfy both my safety concerns, and my partner and I's "I dont want something that looks temporary or bad" concerns.No matter where I put it, it will be visible to guests, unless I shoved it into the closet (which I would not want to do for a litany of reasons, even if it fit).

I think at first when I mentioned that 24" is the minimum I would purchase, I didn't emphasize enough that I would be aiming to get the largest tank (maybe tub?) That fits my available space. If the problem remains that something like a 30x12 or a 30x18, tank or tub, just won't last long enough for a BCI/BP until I move, I'm willing to accept that.

If that's the case, I'll probably spend some time looking into other species, like KSBs or the earlier mentioned pythons. A dwarf locality would be awesome, but like I said, I think it would be difficult for me to find, and there is a not a lot even on morphmarket within a price range that does not make me hurt a little. I do like corns/hogs, but they would not be my first choice after a BCI/BP.

Thank you again for all the replies! I'm really looking forward to going to the con, whether I get anything or not, and whatever snake friend might be in my future. I've got time to decide and deliberate, after all.
