If I were you I would just work with it. Tanks are a little more attention in terms of humidity but I like the display aspect. If my Boa were closer to full grown I would have her in a PVC or similar enclosure. Until then it’s a matter of economics. My Pastel is in a 40 gallon and most likely it’s big enough for her even full grown. I beleive it measures 36”x18”x16”. It’s wrapped in foam board and top covered. Temps are awsome and it just needs a spray down once a day.
I have an ultratherm 11” x 17” heat pad and a CHE 150 watt both on thermostats. Once it was set up it’s really not a big issue.
