I'm getting worried about Quicksilver ... he has what looks like a case of bacterial fin rot. I just forget what to treat him with >_<

He's still acting fine and dandy, eating well, being a goof. It's just this darned pin hole in his dorsal. I've been watching the hole since Monday night and it has gotten bigger. Any suggestions on how to treat him?

Start with daily water changes (50% should be good) and a teaspoon of Aquarium salt per gallon. If the fin is still disappearing in a day or two you can start adding a medication. I usually have good luck with a combination of Maracyn and Maracyn 2 but anything that treats bacterial fin rot will probably work.

Do salt first though, you should avoid medications if you can since they can hurt the fish or cause resistant strains to develope. Medications should be saved for a last resort.
