Lymphocystis disease in goldfish

I rescued my goldfish around a year ago from someone who was going to throw him into a lake. He was kept in a tank with another goldfish. They could literally not turn around without touching eachother and could only swim up and down. When I rescued them it took them almost a month to learn to swim forward and they would swim backwards and just sink. Unfortunately the other goldfish passed a week or so after I got them. They were in a 40litre tank with water almost black. He’s now in a 300 litre tank and I test the water regularly everything is normal. When I got him I was told he had a tumor. After some research I think he has a severe case of lymphocystis instead. I have booked a vet appointment to get the largest but removed tomorrow but just wanted to see if anyone had any idea what this could be or any treatments before I take him to the vets for removal which will cost me £300! I have attached some pictures

 

I believe the goldfish is suffering from "Carp Pox". Its just another disfiguring fish virus. Even if the vet is able to remove the viral tumor chances are new tumors will eventually grow.

Thanks so much for your response. If it were your fish would you have it removed or just leave it be?

 

I sure wouldn't pay big money to a vet. I would provide the best nutrition and environment possible for the goldfish, and watch for improvement. If things don't improve or worsen, euthanasia would be the next move.

What’s the best diet I can give him? I’m so sorry for all the questions I’m not really a fish person but I’m trying to help this guy just not sure best diet for him? Any specific brands I should be looking for?

 

Any goldfish pellet or flake food from Omega One or New Life Spectrum.

 

its awesome that you rescued them, and prevented them from invading native waterways. but don't spend that much money.

i've used Omega One sinking goldfish pellets and Omega One sinking Veggie Kelp pellet for 4 years.
