I have 3 fish which have developed cloudy like eyes and ich like spots on the eyes and the ich like spots are minor on the fins also. Nothing on the body of the fish. What could this be? They constantly go to the cleaner shrimp so I know it is bothersome to them. I did have a fish that died behind a mass of rock and was eaten almost completly by morning. So instead of emptying rocks I let the crabs finish him off. He died the first day I got him and now it's about 10 days later that these signs are showing on other fish. Any ideas? Thanks
