Hi, I've been reading through the forum and I've seen your name come up a few times as the person to go to about fish problems. My boyfriend posted a thread the other day about our fish kogi jumping out of the tank. Since being put back in the tank he's developed a nasty case of fin rot. We've been adding API stress coat, Aquasafe water conditioner, and aquarium salt and doing at 30-50% water change daily. It looked like it had stopped after the first day but now its back and the tips of his fins are red like they're going to fall off again. I was wondering what you would recommend we do. I'd like to try and start a medication asap seeing as he doesn't have much fin left as it is. I was considering buying Mardel's Maracyn but I hadn't heard anything about it, do you have any opinions?
