I had one once. Had a 4 inch sandbed and that fish dug and dug and never stopped. Burried all my corals that were on the floor of the tank, every 2 or 3 days I would have to level out the sand and dust off the corals , the next morning he would have wrecked it again. He never stopped, I would hear him all night digging digging. The water was always cloudy. He was the fish from Hell, I ended up taking him back to the store.
BUT, you may get one a bit more mellow. They are beautiful fish. I just think mine was neurotic.
