Brewer - the harlequin is a kind of wrasse, actually a very gentle fish for the msot part unless you are a shrimp or crab! He has left my emeralds and my CBS alone totally but my peppermints may have dissapeared - I moved most of the small shrimp to other tanks before putting him in.

Vinh - I thought about that but I wanted to have the extra water volume , I guess I could do 2 smaller tanks.
