I like my yellow coris wrasse the down side is the first one was a jumper this one is much more calm and laid back, and the lawnmower blenny is full of personality.
In my 55 I have a clown and a royal gramma that is 3 years old now and a lawnmower blenny and wrasse. I do stock lightly but my tank is very healthy and the fish are pretty much stress free. The clown and the blenny gets into it every once in awhile but it doesn't last long. The blenny is the aggressor by the way.
