luner wrasse? are they dangerous?

[karlyhui]

I brought a small luner wrasse ( 3inch) on a impluse buy. I really like the adult coloring and sharp teeth sticking out.

I am scare that they can be dangerous to my other fishes now.

I currently have a 4 to 5 inch blue face and a pair of maroon clown in a 120 gallon tank.

The pair of maroon gold stride are very small, the male is only 1 inch and the female is 2 and 1/2 inch.

Thanks.
