I had ich in my 240 gallon tank, and treated with hypo for 5 weeks. My emperor was eating great during the treatment, but stopped eating more than maybe a bite a week ago. I am in the process of raising my salinity back up now, hoping that would make the angel feel better and eat, but he is not eating at all, and his stomach is sunken in. There is no sign of ich on the fish. Could this be from the hypo treatment, and does it get better when salinity is raised to normal? Garlic soaked food doesn't impress him. I'll try the clam on the half shell tomorrow.
