I have 3 surgeons in my 200, a Sailfin, a yellow eyed Kole and a regular Yellow Tang. There's a definate pecking order in my system, especially when I forget to ad seaweed for a couple days. When I first got him, the Kole was the smallest and got bullied a lot. His spines were removed when he was caught (but he doesn't know it), probably to keep him from poking holes in the bag during shipping. Anyway, I think the scrapes and scratches are distributed equally amongst the Tangs, and they ALL stay away from the clowns :lol:
