My percula clownfish has a small line of tiny, white dots along its left side right by its lateral line. Sorry no picture, but my camera won't take a clear close-up shot. Could this be Marine Ich or some other fungus? I am going to quarantine him in my 5 1/2 gallon for the time being to keep my Bicolor Angel from catching it too. What could this possibly be? Thanks in advance for help.
