My brown scopas sail fin never stops eating off the rocks she's so fat and apart from when I put a purple sail fin in she's never shown aggression. She almost killed the purple tang though I've never seen anything like it. Her eyes turned bright orange and she went mad.

Looks like a well established, heathly tank that.  You going to start a tank thread, and share a bit about it with us (oh, and lots of pics of course)?

Have a look here:
http://reefbase.co.uk/members'-tanks-6/

Just start up a new thread in there, and tell us a bit about your tank, stock, etc.  Add as many pics as you like.  Typically, people then update it as they add fish, corals, have questions specifically about their tank, update us on recent events, etc. 

Thought I'd share my picture.

Thanx. Love it at night time. X

I just have the one as I only have a 240 litre, a Yellow Eye Kole Tang. Dominates the rockwork and despises any gobies or blennies by relentlessly chasing them until they starve. Not sure if it is male or female. It always used to hunt for food side by side with my Melanurus Wrasse. He / She is always active pecking away at the rockwork and glass which you can hear..........makes me smile when it pecks on the back of hermit crabs shells, I can see both their surprise and annoyance at this. In my original tank I had a Unicorn Tang which I loved and would definitely purchase again when I eventually upgrade the tank size. Great active fish with beautiful coloration. When it is not out and about I can always see the yellow eye spying from a dark cave. It took me blooming ages to get this shot due to the speed of it.
