purple bested yellow

Well when I got up this morning I found my yellow tang stuck between two rocks not sure how he got there like he was but i got him unstuck but he wouldnt swim...

I recently got a purple tang. I know the yellow wouldn't leave the purple alone. I never saw this but I think the purple might've got the yellow with his barbs. I could really look at the yellow well enough to find any signs of injury but I have nothing else to explain his lack of movement after being freed from the rocks this morning.

Any other theroies? I bet by the time I get home he'll probably be lost which sucks!

 

Rode the current flapping his fins the hit the sand. My wife says he is a pale yellow/white color. I think he didnt make it.
