I have a lovely half moon betta named Kevin. About a month ago, I noticed a bit of fin damage, so I did all the usual things for fin rot- water quality, salt, etc. It didn't help (in fact, continued to get worse). I've now been working for a month using everything (Jungle Fungus eliminator, more salt, melafix, etc etc) and now his fin rot is so severe I'm afraid he's having trouble swimming. I've had him for over a year, and not sure what caused the initial problem, but I'm very very concerned. I've read a million blogs that all say the same things- which I've already done. I've ordered some Maracyn2, since that's the one thing I haven't tried yet... any other advice?
