No, I didn't treat them for anything. They actually came out of QT earlier than I wanted due to some mechanical problems with some of my QT stuff. They had been eating well, looked great, and showed no signs of having any problems, so I decided to go ahead and put them in the display. They have been eating cyclopeeze and frozen spirulina enriched brine, as well as some formula one flakes and even some bits of nori that swirl around as my foxface tears it up. Going to be getting some other foods to mix things up as well.
