My goldfish is about 3 years old and for the last few months she keep developing lumps under her scales which starts really small like a bump under the scales and grows bigger and it finally comes to the surface as a white fatty wort type thing and then after a few days it falls off (about the size of an eraser at the end of a pencil). At the moment I can see about 4 at different stages of the growth process. Took her to the pet shop and they guy confirmed they feel like fat but has no idea what they are.

I have kept her with the other fish and run a course of anti-botics in the tank. Still waiting to see if that helps. Any advice?? (She seems happy and not distressed)
Thanks

Hi! Could you possibly post a pic? It sounds like it may be viral. Viruses can cause odd growths and bumps that will disappear as the virus runs its course. There is no treatment for viruses but maintaining ideal tank conditions (lots of water changes, not overstocking, limiting stress & keeping ammonia/nitrite zero, nitrate under 20ppm) will help keep a fish's immune system strong. A good diet will help keep the immune system strong as well.

Thank you for the pic & video! Can you please post your tank size, stocking, water change schedule & water parameters? In the video, it looks like theres quite a few goldfish in there. Addressing any water quality issues is the first step in addressing health issues in fish. Do you have a qt tank?

Thanks for your reply. We have a 100 litre tank with 6 fish. She is our biggest. We change three quarters of the tank water weekly and monthly we vacuum the bottom and change 90 of the water and scrub all ornaments with a toothbrush under fresh water. We clean filter weekly. We check ph levels weekly too.

Thanks! Ok, unfortunately, 100l is only @26g. This would be suitable for a single goldfish and no more. Do you have test kits for ammonia, nitrite & nitrate? These are the most important tests in a fw tank. I would strongly suggest investing in a liquid test kit such as the API fw master test kit so you are able to monitor these levels daily and do water changes as needed. I honestly would suggest doing water changes much more frequently right now until you are able to get a test kit- atleast 50% every other day. I would then look into purchasing a much bigger tank. When you are able to do this, I would keep the fish in question in the 26g and move the rest to the bigger tank. We then can properly address his situation.

Right now, it would be difficult to try and do any type of treatment because you can not isolate him. If he does have a viral infection, your other fish are at risk of being infected. From the redness I can see in the pic on his body, he looks like he has a bacterial infection as well. Please ask if you have any questions!
