What is this line on my tang?

[ps2cho]

I can't get much of a shot in QT...she just hides in the PVC pipe.

 

There is a white line that goes across her belly, and its a tad brown.

Any ideas?

Coral sting?

I've seen yellow tangs get white stripes aftet lights go on. And then they disappear.

I think its something that happens during sleep or lights out.

Perfectly normal for this species. If you look very closely, you can actually always see it, though it has the usual yellow tint during the day in healthy individuals. The stripe becomes visible at night or during stress/aggression.
