Lumpy my oranda has been listless for about 3 days. This is not like him at all, he's the liveliest out of all 5 of my fish. Today I noticed that a part of his wen was swollen and in the past hour it's gone quite red. I've been doing regular water changes to keep the tank as clean as possible for him. My other orandas are their usual selves so I don't think its a water quality issue
Has anyone else experienced anything like this with their goldfish? If so what is it and how can I help the fish?
