I have also kept a cleaner wrasse briefly with my seahorses. I had similar observation for it as for the yellow wrasse...fast swimmer that weaves around in the tank. 
  
It never really bothered my horses. I have never seen it pick on them or anything. It did compete for food, in the sense that it took a piece of mysis away from a stalking seahorse, before the horse made up his mind to strike. The horse didn't seem to care, he just moved on to the next piece. 
  
Then one day, I found the wrasse dried up on the floor...then I realize that I got myself a jumper :S
