I think your Melanurus wrasse is actually a Richmond's wrasse (Halichoeres richmondi). The difference being, on the Richmond's the stripes are blue and appear like a chainlink (much like yours), where as on the Melanurus the stripes are red/orange and more uniform.
Beautiful wrasse though! I see Melanurus all the time but have never seen the Richmond's wrasse in person! Gorgeous fish! I'd gladly take him off your hands if you happened to be swinging through Calgary anytime soon
