yellow Tang with White stripe on sides?

[Jfannin]

ive had this tang for going on 3 years know and just noticed a white stripe on both sides of my yellow tang, and they wasn't there yesterday. up very close it looks like clusters of raised circles. never once has had any problems before. he is kinda fat and very active.

any idea as to what it might be?

All yellows have that but it usually doesnt show up well unless their stressed.

hum maybe the water change i did fallowed by a lights out made him mad. i normally do my WC in the evening but decided to do it early.

Could be, i think a lot of the zembrosas (spelling?) are like this? i've seen purples with a purple line and yellows with the white.
