I got a Mandarin from someone that had it in a well-established tank. By the evening of putting it into my main tank, it was showing SW "ich" spots, so I put it into QT. Did a FW dip & the spots were gone completely--never came back. The fish has been in QT for >5 wks, so I figured it was good to put back into the main tank. That was this morning & now it's got spots again! None of the other fish in that tank have ever had it. What's going on???
