How much height do BPS need??/

I didnt get a tub tonight because i found some good sizes but they were only like 6-7 inches in height, how much heighth do they need? is 7 inches enough? thanks for any help

7 Inches is plenty as Balls are a ground dwelling species. Extra height will be more difficult to heat and may stress out a young Ball.

thats what i wanted to hear, thanks for the info
