I have a foxface that I have had for about 4 years now. It has been fine along with the other fish up until recently. His fins look as if they have been chewed on. Granted things have been real hectic lately and the tank hasn't been getting the attention it deserves. Can someone take a look at this pic and let me know what it is and what I can do to help my fish. I am in the middle of a cleaning cycle now with my tank, and I am worried.
