Looking for advice. I have a 90 gallon reef tank. It has been set up ~ 4 months. Over the last 2-3 weeks my flame hawkfish became unthrifty and pale. In the 1st week it was off feed, eyes were cloudy and bulging, and marked decrease in motor activity. during the second week improved, but low appetite, more activity, still pale, and eyes more clear. This passed week - more thrifty (believe will survive) but still pale. Any idea. Other fish in the tank appear healthy; although one tang has a unilateral mild bulging/cloudy eye.
If anyone has any knowledge/experience, I would appreciate your comments.
