I need a bit of help determining if I'm dealing with fungal or bacterial fin rot here.
About 10 days ago, I noticed that the edges of a couple of Sushi's spikes (crowntail) were looking odd; they were bent over a bit, and looking "dead". I immediately started giving him three daily salt baths, but it wasn't improving, so I added Jungle Fungus Clear on Thursday. Guess it didn't help, as things started looking a bit worse yesterday. He's also had a small hole in another fin recently.
Today, he's still only got four spikes infected with this. All of them are on the same fin and close together. It's odd... because I thought fin rot moved much faster than this?
I happen to have Maracyn-2 on hand. Should I try this or maybe continue with the second dose of JFC?
Attached picture shows what I'm talking about. Note that his fins are naturally black-tipped, and the ventral fins are naturally white-tipped, so that's not a problem.
