Hi All - I had a clownfish in my main tank come down, and eventually die from, what I think was brooklynella hostilis. As soon as I thought he was sick, I moved him to a QT tank and started treating him....he died in the QT. My main question is do I need to leave the main tank fishless for 6-8 weeks like you have to do with ick, or does the parasite not live that long? Thanks.
