I started treating my 100 g tank with prazipro 1.5 wks ago... Now my festae, thai silk, and green terror are having more white stringy poop than before... otherwise they are still very active but appetite is noticably down. Is it common for prazi to make them have more white stringy poop to eliminate it from their system or is this disease getting worse. The water is also heated to 86 degrees and i'm adding salt periodically. Any response would be appreciated... thanks!
