My yellowtail blue damsel has a faded patch on the top of his head with a white patch in the middle. I have never noticed this before and am worried. No new fish have been added for almost 6 months and my parameters are very stable, except for pH, which swings from 7.9-8.4, depending on the time of day. The patch looks like a cross of marine velvit and HLLE. The fish is acting normal and is eating properly. Pictures are not posible at the moment but will try to get one up ASAP. Any and all help would be greatly apreciated!!!
