I have a blackmoore goldfish who has a variety of ailments, most of them I'm assuming from genetics and poor breeding. I want to know if there is anything I can do to give him him a better, higher quality of life.
Gus (the blackmoore) is about 2 years old, was well cared for from purchase, but the original owner gave him to me when they went to college. Gus is blind, has deformed gill covers, and the most troubling recently is that he has developed a tumor.
He's been blind since I got him, his eyes are cloudy and his pupils are oblong rather than circular. His "bulges" also look poorly formed compared to my other two blackmoores. Gus also has a milky appearance around his head, which I think is from a thickened slime coat, but I'm not sure. I did try treating with PraziPro for flukes, but didn't notice an improvement in behavior or health.
The gill covers, while seeming to function well, are not shaped like they should be. They flip out around the outer edge, instead of being flush like they should be. I'm worried that there is an underlying cause for this?
I'm mostly worried about the tumor that has developed on him though. It's on his left side, near the back of his dorsal fin. It appears to be growing (and I don't think he had it when he was first given to me, about 6 months ago) and feels pretty fleshy. He's also become increasingly unbalanced since developing this tumor. He was always a bit unsteady, I'm assuming because he's blind, but lately he has been tipping onto the side with the tumor, like it's too heavy. Sometimes it gets so bad that he's completely on his side when he's resting.
As for the tank setup, it's a 90 gallon cycled tank. PWC (25-50%) are done weekly. It was a bit neglected while I was also away for college, but never to an extreme point and all water parameters are back to acceptable ranges. He's housed with 4 other fancy goldfish, which can make feeding difficult, but he usually gets a few bites to eat.
So, a) is there anything I can do about his tumor? I've looked into vets who may be willing to operate, but obviously I'd prefer to fix things from home if possible. And b) any ideas as to how I can make his life better and easier?
I've attached pictures of his eyes, a top view for the gill covers, and a picture of the tumor as well (not sure why all the pics are sideways).
