So I resantly got a purple tang. I already have an established scopas tang In the tank. When the lights where off they were fine as soon as the lights came on the battle started the scopas wouldnt leave the purple tang alone. I did a minor reagraning of the rocks before I put him in didnt help any. Doing some research I am finding that 2 tangs will always fight adding a 3rd tang may help the situation. The purple tang is temporally in my fudge Looking for any thought or suggestions.
