can't decide to put my ball in a tub.

I always had a hard time keeping temps and humidity in a tank. It was the biggest relief when I got my tubs!

Keeping proper temps/humidity in a tank is very, very hard! Keeping them in a tub is very easy and it takes minimal effort. You just have to make sure the ambient temp isn't too cool and you have luggage straps or binder clips in order to secure the tub to prevent escapes.
