I found about 4 white spots on my blue hippo, powder blue and longnose butterfly fish yesterday. Now the blue hippo has 8 or so, powder blue 6 and the butterfly fish about 3. Should I QT these for a few days or just see if it gets any better on it's own. I have hydrozoa's all over my tank glass (white spots about the same size as are on the fish), so I was thinking (maybe hoping) they're just hydrozoas along for the ride. I'm going to try to do a freshwater dip tonight to see if I can get rid of the spots. This is not going to be fun.
