      Look for behavioral indications that parasites are attacking your fish such as the fish rubbing against the sides and bottom of the aquarium tank and the aquarium plants. Your fish may also try to leap out of the water and plunge down to the bottom of the tank. These behaviors are a result of the itch your fish feels when parasites are attacking it.

      Sprinkle one tbsp. of non-iodized salt per gallon of water into the aquarium. Non-iodized salt will kill the majority of parasites without harming your fish. Do not sprinkle too much salt into the water, however, as a larger amount will upset the aquarium environment and harm your fish. Allow the fish to swim in the salt solution for one to two minutes.
