We diagnosed my male veiltail with lymphocystis a few months back. He has been in strict QT ever since. About a week ago I noticed he was acting lethargic and clamping. I come to find out his heater had failed on me. I got him a new one, but that did nothing to alleviate his lethargy and clamping. About 3 days ago I noticed he would periodically rub against the thermometer and oak leaves (I keep in all of my tanks for the tannins). I can see nothing visible on his body aside from the lympho infection.

I have on hand AQ salt and can salt his tank tonight. I'm worried that he either has a secondary parasite infection or what we had diagnosed as lympho was actually a parasite. Shortly after he was first diagnosed he went through 7 days of salt treatment that appeared to have no effect on the site. I have included a picture of his infection taken in March. His only history of disease is minor fin rot and tail biting. He is about a year old now.

Please advise. Thank you.

Perhaps try some stress coat if he's still rubbing.

He might have contracted ick if h's been stressed, so it could be possible that it was just the start of it.

How is he doing now?

Well unfortunately he died on Monday. OFL and I figured out that he had gill flukes. I was trying to treat him with garlic and Prazi, but he just stopped eating. I found him dead that evening.

I'm so sorry.
