reindeer wrasse

has anyone seen them or know much about them .. i have seen pics of them and im sure i have seen them in my lfs but there is always a different name on the tank .. could anyone give me some basic info on them ...other names they go by ,how big they get ,are they aggressive ..can they go with a yellow tang.. thanks all
 
maybe if i describe the one i saw in a book it will help out ... it was brown and white ..well more like white with brown circles i thought it looked similar to a baby panther grouper but it was written to be a reindeer wrasse
thanks again all
