I have a telescope eyed fish and one of his eyes is enlarged and has some kind of bluish-gray ball on his pupil area. Only one of his eyes has the problem, so he looks funny. I know telescope eyed fish tend to get calcium build ups but I'm not convinced that is what it is. Would that cause his entire eye to swell? Help!!!

when you say inlarged are you talking about around the eye like the sack?

Today my fish died

Oh, I'm so sorry! I would have responded sooner, but it was really hard to tell what it could have been from your description. Fish can get swollen and cloudy eyes for several reasons: physical damage, parasites, and bacteria or viruses. This sounds like it was probably bacterial. Again, I'm sorry. It's so frustrating not being able to help our pets.
