6-line aggression question

[fishoholic]

Ya the 6-line is bizarre he totally attacked the cleaner wrasse and yet he leaves the little fairy wrasse alone, I don't get it The other fish in there are my king angel 3 triggers and a toby puffer so I don't think he'll try anything with them however I do have a mandarin goby which after hearing what Tony posted I'm a bit concerned now. He's never shown any interest in the mandarin so far but I don't really trust him now.

Still think I might catch him a toss him in the reef but my red corris wrasse (who I can't catch out of the reef tank for the life of me ) kept chasing the 6-line into the overflow so I'm not to sure about that. Of the 6-line is bigger and meaner now so maybe he'll hold his own now.
