Hello!
Need help identify what’s going on with the left fin of my pearl gourami. When he is looking at you it’s the fish’s left fin. You can kinda see that there looks to be some kind of swelling? It’s kinda pink where the body connects to the fin. The other side doesn’t have it.
He is swimming fine at the moment but I want to identify and treat as soon as possible if it’s an issue.
Thank you everyone for the help!
