I just upgraded Toby to a large exo-terra cave, since his medium was fitting like a small hat. He was literally squashing himself in them, to the point where his skin looked dented. So I finally got him two identical large caves (also exo-terra), and now his 28qt tub looks REALLY cluttered... there's barely enough room for the water dish, which is pretty small. Should I cut down to one hide? His tub has a dark blue cover, which should feel pretty secure, and he's going into a rack system soon.
