I just noticed my two female Bettas have pretty bad fin rot, so I used to the store, and bought some Malefix. I don't have a quarantine tank, so I am currently keeping them in a bucket. Do I need to keep them in a bucket that has no equipment, or should I use my community 20 gallon tank? My Angelfish has had some minor fin rot, so I have been treating my community tank with 50% daily WC, and hydrogen peroxide. Any advice is welcome, as I haven't had sick fish before.
