I just read your post "A bunch of sick bettas" and in there it said that you shone a flashlight on the tank and it looked like there was glitter? Did anybody mention Velvet? I'm not sure if that would be a sign of Velvet but it does look like a gold dusting on the fish when you shine a flashlight on it.
So, these other two fish... should i be treating the whole tank (including the other fish) for the fungus because with Watson it showed up too late and I don't want the same thing to happen again???
Thanks for all of the support. I know I suck at the fish thing but I am trying really hard to save the other two! Also, should i have my bio filter out, I pulled it out last night but I am not sure about that either. Thanks
Check the medication instructions... some are safe for the biofilter.
If you take it out, you will need to keep the bacteria fed and oxygenated. A simple way of doing this is to put it in a bucket, plug it in so it will be aerated and sprinkle a little bit of fish food in the water so it will feed them as it decays.
