My QT tank has now turned into a full fledged "assisted living tank" as if it is viral, it will come and go. The fish is active and eating well. I will watch and document. A new fish keepers disease for me to learn. Guess I'd better pick up another quarantine....I think it's possible, but it may be too early to tell for sure.
That's sad.. have you had the Lionhead for awhile? If you can keep the immune strong and the water perimeters quality will the fish mange ok living with the virus? My new Ram has the company of 2 female Leopard Danio's who are supposedly not affected by Lymphocystis. They will remain a trio.I have a lionhead goldfish in my 20 gallon tank with a virus, I think it's a cyprinivirus. I'm not going to expose him, or any of the other fish in the tank to any of my other fish.
