I had a filefish in my tank to take care of some aptasia. Once the aiptasia were gone it started nipping at lps, specifically a torch and hammer, both with multiple heads (8-9 each). I removed the filefish but there was significant damage to the torch and it slowly receded until it died several weeks ago. Now my hammer which only had one head nipped has been retracting the polyps on the entire coral for a few weeks now. Any advice?
