Okay so I just bought this fin rot treatment called API T.C. Tetracyline for my neon tetra that is suffering from fin rot. I was wondering do you think I should just stick to daily 30% water changes and hope that it cures my tetra's fin rot? Or should I separate the sick tetra from the others and treat it with the Tetracyline? Because I'm kind of worried the tetra might die if I separate it from the others. On top of that apparently this fin rot medication does some sketchy stuff like makes the water red, creates foam and kills healthy bacteria.
