I'm so worried about my new Blue Tang! I received him/her 2 days ago (ordered online). Today I went to see my fish and it had some type of erosion under its fins.
I have 1 picture that is of reasonable quality: http://picasaweb.google.com/mysaltyf...04266289129650
It's hard for me to take photos, but I tried. I also took a video and posted it on youtube: YouTube - 9/19/09 - Blue tang problem
Please help me identify this. Is it ich? Something else? What should I do?
BTW, Yesterday I started Cuppermine treatment, so the water has half the treatment amount now (and the 2nd half is supposed to be added tomorrow)
