Coris Wrasse with Skin Issue

[John Minnix]

All,

I've had my yellow coris wrasse for about a year now. Up until yesterday, it looked pretty good. Today, I notice it has scrapes or sores on in its skin and its tail is frayed. Most of the places are whitish but one is redish. I have a Christmas wrasse as well. Today, the Christmas is going after my yellow coris relentlessly. It hasn't done this since the first day I introduced the coris to the tank.

Is my wrasse sick and is being picked on by the Christmas due to frailty, or are these injuries from aggression? Pics below.

What should I do from here? It's going to be darn near impossible catching the coris to get it into my QT, unless it is practically dead. It is way too fast to catch.

Thanks,

John

P.S., I just fed the tank and he ate hungrily. No issues there.
