Tweaked Tang? Hi, <Hi there! Scott F. with you today!> I have just added a beautifully healthy eating Yellow Tang. He eats the seaweed I put on the clip as well as blood worms. The worms are surprising because I thought the Tangs were herbivores. <Well, tangs are primarily herbivorous, but they do eat lots of different foods...In my experience, there are few foods that a healthy tang will refuse!> Anyway, When I look at him from a certain angle his right fin seems to have a white shading on it. It is not salt or sugar like Ich. I am a little concerned. No rapid breathing, no scratching yet. But could this just be coloration? <Hard for me to be 100% certain from here, but I'd hazard a guess that this may be an area of different pigmentation...In the absence of other "symptoms" of disease, I'd just keep a close eye on him and not get too stressed out about it! If the situation changes, we can re-assess this, of course!> Thank You for your time and help. Christy <Any time, Christy! Regards, Scott F> David W. Evans
