there are a couple fish called christmas wrasses. there is a one that follows parrot fish around and eats the inverts they stir up. this type also gets pretty large. there is a smaller wrasse also called a chrismas wrasse that is invert safe. this is mine its an old pic
It is very important to make the distinction between the two - one is pretty big and definitely not reef safe...the other is more similar to coris type wrasses. So be sure you know which one you mean
