It is fairly large but certainly doable. My Ball has been in the same 40gal tank her entire life. When she was young I had good hides, plants, logs, moss, etc. She did great and as she got bigger I reduced what I had in the tank. If you want to use the tank you are getting ready do it. Just make sure you give the snake plenty of cover and concealment. Plenty of people have done just fine like that.
