Yellow Tang Back n DT after 80 day QT

[azsoccerpop]

I set my tank fallow in late december 2016 and on Friday 3/17 I put 3 fish back into DT after 1 month copper and then waiting for the Ich in the DT to run the 80 day cycle. The Clown and Blue Hippo Tang are fine and eating but the Yellow tang has gone bonkers. It flies around the tank never slowing down. It stays to one side and swims back and forth non stop occasionally pointing it's nose upward. It will eat frozen mysis when not spooked but has not touched nori on the clip for a day now.
Is this a reflection and territory thing or is something wrong? It was pale faced for the last week in QT but little by little color is coming back. I don't want to have to put it back into QT again but not sure what else to do.

Just a guess, maybe stray voltage? Or might be just adjusting to the new tank after so long in a small qt.

NOt sure on voltage.

I hope its adjusting I wold hate for the little guy to have gone so long only to stress himself to death in the big pool. I will keep feeding frozen hoping he calms down and eats a bit more.

Last night the lights dimmed to 20% blues and the Tang seemed much calmer. I am thinking it may be posturing at its own refection in the glass? The face is still pale and has pronounced lines but the Nori (I added garlic)was all gone this morning and it is still eating so I am hopeful the stress goes down and it does not get sick again.
