I added a pair of harlequin shrimp 2 days ago, and they are not eating. I noticed that the asterina stars (only a few of them) made a break for the glass when they were added, but the harleys arent going for them. I placed a cc star in the tank and they are still not going for it. Today the harleys came out of hiding and I dropped the cc star right in front of them, and they still have taken no interest in it. Has anyone experienced anything like this when they added new harly's to their reefs? Am I missing something here?
