I know there are tons of messages about fin rot on here, but I don't think I'm repeating a question...
A couple weeks ago, I noticed that my betta had fin rot. I started using Melafix, and after a few days his fins were transparent at the ends and healing. After a week and a half, I stopped adding the Melafix because he was mostly better. Two days later, his fins were more damaged than ever, with a huge tear in his dorsal fin. I've had him back on the Melafix for a couple days, but I'm really worried.
So, my two questions:
At this point, should I try something besides Melafix? Maybe Jungle Fungus Eleminator? Something else?
And, this was a new thought, should I not be running his filter while I've got these medicines in there? There's charcoal in the filter, and it just occurred to me that the charcoal could be removing the meds.
Thanks so much for your help, guys!
