A.P. Pimafix.

I'm not usually one to medicate...figure it's a natural tank, so let nature take it's course(the excepetion being Ich...not had an outbreak of that since the first month the tank had fish, but I DID use quick cure..and it did the job admirably, with zero loss of fish or any other resident plant or invert).
However, I recently had one of my mud minnows develop a severe case of fungus on one of it's pectoral fins(fin was eaten to the base, and it looked like a cotton ball the size of a large BB). I'm assuming it was battle damage..but regardless, I figured I wanted to at least try something, and given the build of my tank..the fish was simply uncatchable, so it was a "whole tank treatment" or nothing. I had let it go for 3 day's, hoping that the fishes natural immunity would do the trick..but alas, it just got worse. On the advice of a LFS I trust, I tried A.P.'s "Pimafix", as it would not affect the bacteria in the tank. I have to say..that literally within less then an hour after the first treatment, the fungus was COMPLETELY gone....nothing remained. This, after getting progressively worse for several days.
Today, the fish was out and feeding normally, and the only sign of the damage was the much smaller size of the fin in question..although it appears the fin is making some small amount of re-growth, even.
I know it's an "all natural" cure, and generally I'm skeptical of those..but in this case, unless it was a freak chance miracle self cure..the stuff worked like a charm(and it smells good, also!).

I've been using it for a few years and it seems to do the trick.

What is that stuff? Sounds like a wonder drug [not meant sarcastically].

BTW, my female mudminnow, who had ragged, slightly fuzzy fins around the time you first reported your problem, layed a batch of eggs [which have hatched]. I kept her seperated from the male until recently and her fins healed on their own with just a healthy diet of earth worms, and various frozen. Apparently the fin damage was from all the overzeolous lovin from Mr. mudminnow.
I have now reunited the pair and the male pays no attention to her whatsoever. Looks like she's out of the woods.
I don't mean to compare your situation to mine, only that I remember we were both posting on our mudminnows' fins around the same time.

IT'S THIS STUFF. CAN'T FIND THE MANUFACTURER ON LINE QUICKLY...

I like many of the aquarium pharmaceuticals products. I've added a link below that includes the MSDS sheet.

I've used a combination of Melafix and Pimafix for fin damage on tropical fish. The fins always regrew quickly with no fungus. I've never used it on existing fungus. It might have irritated my kuhli loaches, they swam around in circles after I used it, but they'll do that after a water change sometimes.

Is this stuff usually available at local fish stores and large chains (i.e. Petco)?

It's made from bay oil. Interesting.
I think I've got bay bushes in the landscaping at work.

Yes, most places should have it.

Ok, add "cloudy eye" to this stuff's apparent miracle cure list.
3 day's ago, I had one of my black banded sunnies just about blind in one eye due to haze, with the other eye not that much better. Both my other ones also had haziness. I put this stuff in, and today..it's totally gone. I also did a large water change, so not 100 percent sure this was the cure..but a "white spot" on the INSIDE of the bad one's bad eye, that had been there since day one...is also completely gone in two days, and THAT was not due to my water conditions as again, it came with the fish.
I really am starting to like this stuff...

Interesting.
It's counterintuitive to me to think of an astringent [bay oil] working for an eye problem. Makes me think the cloudy eyes were fungal in origin.

I've never used pimafix before, but with melafix, when it says "promotes the regrowth of fins/healing" it means that it will irritate the hell out of the damaged area and causes the cells to regenerate at a faster rate. Cruel, but it works.

Well, you may have been right anyway! I did a big "prune" today and now have much better lighting, and can see that the haze is actually still there. It's not any worse, but not really any better either. So...back to square one. I have some maracyn I'll try first, and if that does not work, I"ll try tetracycline(after a water change of course). The fish themselves are not showing any signs of discomfort or any other health problems, so still not sure what is going on for sure. I am really only "sure" of the haze on one of the fish...but the others may have some(as you can tell..it's right at the edge of "is it, or isn't it?".)

I have used MelaFix and PimaFix for years now and they have both given very good results in my experience with the drugs.

Yikes! Sounds bad, but when I've used it I have not noticed any signs of discomfort in the fish.

What makes you say this? Anything I put on one of my own cuts that is supposed to promote healing doesn't irritate me...
