Well, after a tail mauling one of my guppies has developed fin rot despite treating the tank to prevent it. I added Tetra Medica on Monday but he's got a lot worse. I've read that you should use a broad-spectrum antibiotic, is what I used up to the job?It specificially says it treats fin-rot.
It says to repeat the doseage after 7 days if no improvement is seen, I doubt he'll last that long as he spent all day hiding to the extent that I thought he was dead and gone, would doing a 20% water change and repeating the treatment now be too soon? I don't want to damage the healthy fish.
Any help would be appreciated, the local lfs shuts in an hour so if I need anything I'd like to get it tonight.
