Did my foxface kill my tang?

Today I woke up to my powder brown tang dead on its side which look like in impact wound. All my parameters are perfect. Just wondering is it possible that he could have died from my foxface?

I doubt it. I believe the fox face spines are for defensive. How big of a tank? Were any of them new additions? Does the impact wound look like spines punctures it? Again I doubt the fox face would do that.

It does look like a puncture wound only because one side has discoloration compared to the other side(shown in picture) my tank is a 125g and no new additions. They had no problems before and would eat together and no problem but I just dont know how this happened.
