I just wanted to be clear. This tub is acting as a hide right? Something the snake will be able to come and go from as it pleases? If that's the case you could probably get away with a little more coverage on the UTH. With such a large tank and such large hides I would suggest placing a smaller hide within the hide, just so your snake will feel more secure. Especially if he / she starts to refuse food. Is your snake a ball python?
