eyes

[cattfish]

We have had some trouble with the tank. We lost 6 fish in 4 or 5 days of each other. At first we thought it was ich, but then LFS said it was something bacterial, probably fin rot. So we have been treating the tank with tri-sulphate. Our coral beauty seemed badly infected with the disease and has been spending most of her time by the cleaner shrimp getting cleaned. Just today her eyes are very swollen. Almost looks like one of those bugeyed goldfish and they are a little cloudy. What could this be from? Not fin rot I expect. I just want to know what our fish have to make sure we are treating them with the right stuff and that we do everything right to get rid of it once and for all.
