All you need to take care of this thing is a sand bed. I've had him in my tank for almost a year and he's never caused a sandstorm and never had a rock slide. They do move the sand a lot but this is good for the aeration of the substrate. You'll just see a little poof of sand every once in a while when they move some. I have LPS, SPS, mushrooms and softies in my tank and they are not affected at all. I'm going to a bare bottom tank so I need to get rid of him. Let me know.
