Attached I have uploaded up some pictures on a Severum in my tank that has inflammation on both pectoral fin attachments. I have never encountered this before and would like some info on how to treat.

I've seen that before in mine. The fish looks healthy and I assume is eating. Last time that happened to just used a broad spectrum antibiotic and water changes. That seemed to do the trick.
