HELP! Fungus or Bacteria?

[flowerpower]

And without water parameters there's no way to tell either. With good water most fish heal right away from fight damage. Do you have a test kit for ammonia & nitrite, by any chance?
Edit: General Cure is for parasites. I don't think it'll do a thing in the world for fin rot or torn fins.

True indeed. My ammonia is 0, Nitrite is 0, Nitrate is under 10ppm (barely detectable), and ph is 6.8. I have the API test kit (not strips). The tank has been established for over a year, I do 30% water changes bi- weekly, use yeast CO2, have two HOB filters rated for 20gals each (one of which has a bio wheel). The lights are timed to go off between 10pm and 8am. The most recent introduction were a few rivulatus that I received from someone. They looked a bit sketchy and I failed to quarantine, which is why I used the General Cure. I have never had problems w/ this tank aside from Ph fluctuations which I sorted out many months ago by adjusting my yeast CO2 recipe.
I will post pics when I get home tonight.

Well alrighty then
Like I said folks-the man knows what he's doing lol
Seriously, you seem to be more knowledgeable that most and if you can't figure out what's wrong it's doubtful we can

When it comes to meds, no. Aside from the generic meds available I know very little. As you can probably tell from what I used, I generally take shots in the dark and hope for the best. In fact, I was all but convinced that this was fungal rather than bacterial before Lupin suggested otherwise.
Anyways, the fish seem to be improving despite the random assortment of meds that I threw in the tank. I've included a pic of the tank but unfortunately, not of the fish in question.
Thanks again to those that tried to help despite the limited info that I provided.
