thank you Kitty Kat - hope thats because you are a cat lover - I am too! My world was cats till our fish came into it!
thats only one of the cysts he has about 4 - we are treating him with myxozin from local aquarium and water been tested which is fine - other gold fish (mini carp) really...
We have had our fancy and other goldfish for over three years. We have know our fancy has swim bladder disease for about a year but he now stays at the bottom of the tank (cant swim) and the other fish kinda looks after him. However, he has now developed cyst like bubbles which are coming out...
