Some people like them, but for best care you really should have a tank with a monstrous footprint and a one foot sand bed for when they get two feet long. I know someone who has one who never sees it and he said that it doesn't do anything to his sand it just sits under a rock. They also bulldoze rocks over when larger and are extremely clumsy and strong. I was looking into getting one and probably won't but if you get one get a male they will stay much smaller. Hope this helps.
