FoxFace and Yellow tang picking on Corris Wrasse.

[b4tn]

My One spot Foxface and Yellow tank have decided that they are best buddies. They used to keep their distance but now the yellow tang follows the Foxface everywhere. They even sleep together! However with this new brotherhood they seemed to have gotten a little territorial. But only towards my yellow Corris Wrasse. If he gets anywhere they decide he is not welcome they chase him around the tank until he hides in a corner. He comes out and swims around like nothing happened until they decide they dont like where he is. Its very random. Is there anything I can do?

As long as it doesn't keep the wrasse in hiding it should be ok, but if he is forced to stay in hiding, than either the wrasse or the aggressors should be removed.
