Have you tested your water?
Yes
If I did not test my water...
  1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.
Do you do water changes?
Yes
If I do not change my water...

I got 5 Boesemani Rainbow Fish and didn't notice one of them had white "fluff" on its dorsal fin and one pectoral fin. It was a very small amount but the fish also wasn't swimming normally. I took the fish back as I don't have a hospital tank right now and am running my UV in the canister as pseudo fungus is bacterial but I don't see any signs of it on any of the other new fish. I wish I'd seen it at the store when they were bagged.

[I answered all the questions below the posting box but I just posted in this thread because I thought it the appropriate topic, not really asking for help. Been a fish keeper for a really long time. :headbang2 ]
 
If ur not seeing any fungus then watch the fish. Fungus comes in as more opportunistic.

It may have been actual fungus if not a pseudo fungal bacteria. Either way the fish likely had lowered immunity, hence a target for an opportunistic pathogen as you said.
