I have 2 silver dollar fish in a 55 gallon tank. They are about 6 years old and have been healthy and happy for a long time. Suddenly, a few weeks ago, one of the silver dollars started having eye problems. a small white dot formed on one of the eyes and every day it got bigger until it completely covered the eye. Once it covered the eye it became fuzzy (almost dead skin like in the water) and became thick, like it was growing on the eye. It started to peel off until there was nothing but a crater in the socket with what looked like the remains of an eye but somewhat discolored. About 4 days ago it started on the other eye and is now that cottony, fuzzy white growth over the eye. The fish still swims slighty and still eats. The other fish stays away from it yet remains unaffected. What's happening to the fish? Btw I took a pic of the growth of the second eye. Please take a look at it in my gallery.

Wrong forum but it looks like saprolegnia fungus.
