Checkerboard Wrasse smooshed lips?

[banditpowdercoat]

My checkerboard "Wrassehole" looks like he's run into a truck! His lips are, for lack of a better description, smooshed. They look broken, and he doesnt close his mouth fully. Appears to have a hard time eating. He used to be lightning quick to snatch krill and mysis. Now, looks like it pains him to open his mouth more than what it is. I just completely emptied the tank, moved and re assembled. Could it be the stress of moving them into a temp tank for 2 days?
