Hi, I’m new here. I have 2 telescope fish which I’ve had for 3 years. They have huge eyes and one of them always seems to have problems with one of his eye. It used to get cloudy and red and then go back normal after I gave him some anti bacterial medicine. A week ago my fish started to get this cotton wool like growth on his bad eye so I went and got some anti fungal treatment and gave him that. So now, a week later, nothing has changed and it’s just gotten bigger and bigger. He’s still being semi normal swimming about, not eating as much and now I’m stuck on what to do as nothing is changing. Baring in mind my other fish has been completely fine this whole time and I have also cleaned the tank before I put the second lot of medicine in last night. Thanks in advance.
