Flukes I think...

I'm actually starting to think Prazipro is reef safe and only kills the intended organisms. Kind of like flatworm exit that only kills flatworms and doesn't hurt anything else (it's the FW toxins that hurt stuff. I know this from experience, unfortunately).

I don't like putting medication in my display tank either, but if you're desperate it's good to know what medications are safe to use.
