I have a problem with my two discus that are in a tank together. They both
were fine yesterday and they are usually very healthy. I have had this tank
established for 2 years with both these fish and no problems. This morning
I noticed something really alarming. They both have these white patches
over their eyes. One eye is almost all covered. I have no idea what this
is and I want to treat it a.s.a.p. Hope someone can help me!! Melissa
