I've recently acquired a Yellow Coris Wrasse which I acclimated to my tank on Wednesday. Yesterday I dropped some food in my tank to see if he would eat. He ate fine and spent the rest of the day exploring and hunting in the open. Today when I went to check on him and he was sitting at the bottom of my tank motionless, struggling to breathe. When I purchased him his fins were torn and he had a tiny bit of pink behind his fins. The fin that is torn the worst is his left fin (as in picture). This is the fin where the red has spread.

Is it an infection? Or bleeding within the fin? What can I do?
