I have a potter's angel that has been in the tank for a couple months now. Today I noticed him nip my foxface 5 times on his side. The foxface has been in the tank for almost a year and has been doing great. I haven't noticed him acting strangely lately and he eats anything I put in the tank (even after the potter's picked on him). One of my wrasses died last night, and the night before last I saw the potter's pick at him a couple times. I really don't know what to do and am extremely worried about my foxface. Is the foxface ok? What should I do? Thanks in advance for any help.
