I agree with the wrasse only. Actually, many different types of wrasse will be effective, fairys for another example. And they will eat other foods that are offered, so you don't risk dooming the fish to starvation and getting your worm problem back.
Once the fish (if you choose to do so) has the population under control, you might then consider treating with Exit. You must be sure to syphon off as many of the deceased worms as you can. Once dead they release toxins that will kill your livestock. Read the instructions very carefully and research it before you do so.
I opted not to use the Exit, but bought a wrasse to control bristle worms, because, let's face it, there are some hitchhikers that we love and I feared the Exit would Exit them, too. I don't like chemicals in my tank.
Using a mandarin is not a good idea. I don't believe they eat the worms and even if they do, without a good lasting source of live food (pods) they generally starve to death.
IDK about the scooter..
