Anchorworms are rare in aquaria unless it is brought by an infested fish. Use tweezers when removing them and be sure to grip the tweezers to as close to the parasite's head as possible. The head is embedded on the fish's skin. Use salt in the aquarium to prevent secondary infections such as fungus. Note that the areas where the parasites were removed will be prone to infections hence the recommendation for salt.
