Dont know if it was my fault or petsmarts but since I got my first albino tinfoil he has not eaten much, very little has a cloudy eye and gets chased by a 2nd one the same size. Each day does not eat or eats very, very little. Today I added pimafix fugus cure will it work, The whole bottle was only enough for one application in a 300 gal. So cant add more each day as the lable says, $10, per bottle so expensive too. What have others used for fungus cure? Does this sound like some kind of fungus?
