I've had my one corn in a 90gal tank since she was 20grams. I've just placed plenty of hides (5+) and low vines/fake plants. It's just a bit more cleaning, but I think it takes me an extra 5 minutes compared to my other corns 20gal. My snake has thrived, and now at over 90grams she seems to be quite content just hanging out and cruising around more.
