My 6 lines wrasse is crazy

[nycfish]

I have 3 tangs, 2 goby & 1 6lines wrasse in a 90G, reef tank. I just wanna put a pair of clown in there, but EVERYTIME that I put in fishes other than Tangs, the 6 lines wrasse will chase them until they die...Why?? I tired to take it out but with no luck.

6 Line

My 6 Line Would Kill Any Other Wrasse's I Put In Tank. Used A Gatoraide Bottle Put Food In It And Sat It At Bottom Of Tank With Fishing Line Around Neck Of Bottle And Snatched It Up Once He Went In
