well... as long as your fish still can find its way around the tank, and can find it's way to food.... i don't see why you need to put it down.... Fishes are not like human... they may not need their sight that much.....
i have a blind dog.. and she has been blind for the last 4 years of her life.... she is till happy with us.. in fact she has learn to find herr way around the house and furniture...
my point is they do not need their sight to live.... as long as they can find food... or you have ways to feed it...
my 2 cents worth
