My clowns didn't want to have anything to do with my cleaner shirmp for a while, then one day i looked in the tank and one of them was right up next to one and you could see the cleaner trying to get those white cotton ball thingies off of him. You could tell it hurt him, cause he would jerk away, then go right back. So i think they do. HTH
