What has your experience been with the Harlequin Tuskfish? I bought one last week and have him in QT currently, along with a squirrelfish. However, I have heard mixed things? Does he bother the shrimp at all? Does he nip at your clam or corals? How does he do with the other fish?
On a final note, beautiful setup! Amazing how you managed to get such a diversity of fish in there!
