Since its just a deformity it doesn't really bother me. And when I clean out her tank next time i think i will do as you said and start a hole for her. As she only digs in one corner of her tank its easy to know what spot to pick for her (top right cornerThe only thing i think that is hard for her is to get out of her water dish. It always seems to be a bit of a pain for her, she splashes all the water out. I think thats why she rarely sits in it.
