I have one, model citizen, always out and about and it seems to have rid my clams of pyram snails. Very cool fish, commonly called yellow coris (but not really a true coris wrasse), sometimes called a canary wrasse. Personally I think they are a very underrated fish. Cheap and far nicer and more useful than the 6,8and4 line wrasses.
I agree with rmalone. One of the best workers out there. You may have the "jumper" designation wrong. I had one for several years until it took the final leap.
I love this fish. I have one of these and a Leopard Wrasse in my tank. They are constantly on the move picking at the rocks. And watching them disappear into the sand bed at night is pretty awesome.
