  7. My shared success with QT’ing fish

    Over the last several years, there seems to be a higher need to QT your fish. Most of the fish I receive on line have internal parasites. This is found by watching for white poop in your fish. About 60% of the fish I get these days have internal parasites. This is not an issue with the fish. The fish come from all the same place…..the ocean. I don’t believe that the fish have very many issues straight from the ocean. Once they are collected they are placed on holding facilities and they are...

  25. Like a 'broken record'...(Quarantine- again)

    I spoke with a fairly advanced reefer the other day, who had a terrible tragedy in his reef that could have been avoided with a very simple practice; one which he should have developed during his hobby "infancy." But he didn't. And he paid the price with lots of expensive dead fish. I've heard this so many times before that it's not even funny. It seems that the longer I've been in this hobby, the more often the same issues keep coming up. We seem to collectively go through periods of...
