A single Sand Sifting Starfish will completely decimate a medium sized sand bed in a few months.
For sifting gobies it depends. If they take food supplements, many will, then there's a good chance they will pick a spot to sift and not venture too far. They have the capability to wipe out a sand bed if they decide to sift the entire bed so it's quite risky.
