He was a small fish not very old and the five anchor worms he had made lumps that pretty much covered his entire little body. Pulling them off by hand takes a skilled person because opening the wounds probably would have had him bleeding to death anyway. He came from a sickly tank to begin with and if these guys were in there as well as the fish lice and ich then his immune system probably wouldn't be able to handle much more. If he had come from a healthier background and I was confident that he had a good immune system I might have tried some medication, but there is not much you can do about existing anchor worms and the ulcers they leave, medication won't fix the wounds or kill off any eggs.
