Has anyone had better good luck with the WHITE sand and not the big color types? Or playground sand? this way they get to dig?

I have tile on the bottom of her tank and all the right lights and ext...

But my wife want some type of sand, Our is a large Juvenile, Body is about 8" with out the tail and is eating LG Crickets Easily with her greens and worms.

Just trying to find out if there is any sand that would be ok?

Thank You
