the chromis don't host it they just swim in around the tenacles and from what i have read most clowns woun't host a giant condy we have 2 clarkies they will host the other type of condys as they do the other one we got the larger of the 2 clarkies will go rub it once in a while but shys away as this condy will try and wrap its tenacles around it so it just test it i think, the 2 cleaner shrimp that you see are still in the tank we had 3 maybe they seen what the condy did to the 3rd one and stay out of reach
