HELP don't know. . .

bought a yellow tang monday afternoon. he was doing fine until yesterday. got home last night and he had two white lines one on each side of his body. look liked somebody had took white out and wiped down his side.
then this morning it has somewhat blended into his yellow color but you can still see where it was. didn't know what it might be.

Sounds normal. YT will fade with the lights off and brighten after the lights come on.
The two white lines are also normal as long as they are not following the spine... if they run straight, no worries.

thanks for the advice. didn't know that about them. last night was the first time i have noticed that about him.
