I bought a Blue tang for my 90g about a month ago and it has been doing very well. I recently moved (tuesday) so I am assuming there was some stress with the move. But my blue tang has developed whites spots from nose to tail fin. They appear almost raised odd the skin. What is this? How do I treat it? Should I be extremely concerned? I just fed the tank and she's still eating and swimming around fine. Behavior hasn't seemed to have changed. Could this be a temp thing?
