guppy;1065976; said:If the worm has an end embedded in the tissue of the fin it is probably one of the many anchor worms, they are relatively harmless but can reproduce and sometimes they can penetrate the abdominal wall and kill the fish. I treat them by gently securing the fish and removing the worm with forceps or tweezers by firmly pulling straight out from the fish until the worm comes loose. Dispose of the worm in the trash. I also swab the wound with hydrogen peroxide or iodine before putting the fish back in the tank, as it can become a site for a secondary infection. These parasites are pretty common among wild caught fish but I have never lost a fish to them or had any problems after removing them.
OK, I'll give that a shoot. Thanks guppy
