The tub is fine, however, I would change the sand for moist potting soil (PLAIN potting soil not Miracle gro!) The sand is a little too abrasive for the eggs. It would work in a pinch, but I prefer the potting soil. She can dig her den and it packs well so it won't fall in on the eggs. I wouldn't put this in her regular viv as you would have some major clean up after. Better to use the tub, then transfer her back to her viv after she lays her eggs. Good luck
