I just switched my adult ball to a 36 qt tub. Temps are perfect, humidity is perfect... I had her in a 40gal long (with 2 hides) and only 1 fits in the tub. I could put both in the tub but shed literally be crawling into her cold side tub as soon as she stuck her head out of the warm side one - there's just not enough room. Her hides are the perfect size for her. I'm sure ill be asked if they're too big for her but they fit her just perfectly she has little room to move around in there and it creates a nice snug fit. My question: do I need 2 hides in my tub? ive seen tubs with one and tubs woth two... i put black duct tape around the outside of 3 sides of it and her thick branch and fake leaves create a dark pocket in the cool side that I imagine she would feel secure. Please provide your EXPERIENCE if you have it. Thank you!!
