Personally if u only have one bp, a tub setup is probably not something you'll want unless your trying to save space. Tubs are used mainly to save space, they are not very visually appealing. Ball pythons typically just chill on the ground or in their hides which makes a tub great because most are not too deep. If you only have one, he likes to climb, and space is not an issue I wouldnt consider a tub until you get more(which you will)
