JackSpades: I'm certainly no expert, but I've heard that you're not supposed to use Melafix with bettas as it can coat their labyrinth organ and make it hard (impossible?) for them to breathe. At the very least, you should check into the accuracy of this - for Piglet's sake!
I read the same thing AFTER I'd already dumped the full dose in the tank
Then I freaked out and had to do a really quick water change
I did some more reading and people seem really divided on the whole issue but I figured that it was better to be safe than sorry and took him down to a 1/5 of the dose (the same concentrate as BettaFix). No problems so far.
Also while I have you guys there one of the other members suggested that after 11 days aquarium salt starts to damage little fishy organs. I'd never heard that before and I don't want to over-medicate. I also don't want to not medicate for long enough and create med resistant fungus / bacteria. What do you guys think? I've had him on the Multi Cure for six days and his fins aren't getting any worse ... not much re-growth but I'm guessing that takes time. I was planning on taking him off the Multi Cure after 9 days but keeping him on salt and MelaFix for a bit longer to help his fins re-grow. What do you guys think?
