i housed my yellow tang in a 30 gallon for a month while i moved, broke down his original 75gal home, and set up a 125gal in my new home. he was miserable, inactive and shy and his great personality disappeared. that is until i placed him in the 125. He's back the way he was; the Undisputable King of the Tank. the whole move was done ever so slowly with not a single fish loss.
So i guess the point is, tangs shouldnt be housed in an aquarium smaller than 75, imo
