Yellow tang question

[Deep Reef]

I bought this yellow tang about a week ago. Gave him 7 days of prazi pro. Currently doing tank transfer for ich. I noticed this white bar on both sides of the fish. Is this normal? I've never had a yellow before and I didn't notice this when I bought him. Otherwise he is eating and acting healthy.

Thanks

Mine has them all the time when he's just waking up from overnight darkness or if he gets really ticked. Otherwise though they're so faint you can barely see them. Looks like yours was aggravated or waking up. Totally normal from my experiences.

Awesome thanks for the help
