wrasse swimming wierd

[m88a2]

i have what i believe is a yellow flanked wrasse (Cirrhilabrus lyukyuensis) for about a month now. He was swimming just fine and still eats like a champ, but when I came home this weekend he looks like he isnt swimming "normal". He is still pretty active but he goes vertical and tilts on his side often. can anyone suggest whats goin on?

Ive seen this in fairly new introduce wrasses when they are stress out.

It sounds as though it may be a swim bladder issue.

i hope its just temporary stress and not swim bladder...is there anything i can do other than keep an eye on him?
