Festae with white worm/parasite looking growth

Tough to say from those pics, but it doesn't quite look like a fluke to me. Perhaps it's just lymphocystis?

No prob. Lymphocystis will almost completely disappear in a stress-free environment. I have seen it on my mayan cichlid before (twice in his lifetime), but usually it isn't present.

Don Conkel once told me "People say that there is no cure for lymphocystis, but I'm telling you that if you put an infected fish in a pond it will disappear!"

He's right to an extent. Fish in a natural environment rarely have visible lymphocystis, although I have certainly seen it in individuals of wild populations before.
