Need Help !! Sick goldfish.

[fishbreeder12]

So my much loved goldfish aint doing so hot. He had something a while ago ,but after salt ,malafix and heat he got better, sort of....He still has cloudy eyes and can never seem to get "fat" like all his other tankmates. He eats fine ,and swims ,but he's litless ,and shows little strength when he swims. and he never gets fatter ,no matter how much he eats. All the other fish in the tank are fine ,and I really want to get Zim back to his original lively self.

Is there anything I can do to help him get better ??

Cloudy eyes are often a result of poor water quality. Please be sure to check your water parameters. It is not surprising goldfish are so prone to infections as they contribute heavy amounts of wastes causing the water to deteriorate rapidly.

Why were you using Melafix, salt and heat?
