wow anger anger , everything i have ever done to fight worms was to put aquarium salt into the tank and crank up the water to 80 and ride it out some people will actually pull the fish and preform surgery if you can see the worm to pull it out but this usually damages the scales also you can try garlic the worms wont like it and it should help to get the fish hungry again then you can always treat the tank but most likely it might be in the sandbed and make a problem that meds wont always fix i have also had to compleatly gut a tank and quarentine a fish to get it healthy again
