Symptoms of arowana outsourcing:

1. Dark body color. The body color will become dull, and the amount of food and activity will decrease. When the parasite remains on the body surface for too long, redness, swelling or ulceration may occur at the parasitic site.

2. Rub the cylinder. After being infected with external parasites, the body will feel uncomfortable, with itching, redness and swelling on the body surface. If they want to get rid of parasites or relieve itching, they will rub the tank or sand to relieve it.

3. Restless. Their personalities will become extremely irritable, and because their physical discomfort cannot be relieved, they will swim back and forth in the fish tank. When they feel uncomfortable, they may jump out of the fish tank.

Treatment methods for Arowana outsourcing:

1. Clean up parasites. Breeders should clean the parasites on the surface of the arowana. If they are larger parasites, they can be pulled out with tweezers. If it is a smaller parasite or parasite eggs, the breeder will need to use drugs to treat it.

2. Prescribe medicine. After the breeders clean up the parasites, they must use trichlorfon or other special pesticides to give the diseased fish a medicated bath. Medicinal baths are used to kill parasite eggs and prevent them from hatching and reproducing.

3. Anti-inflammatory. When arowanas are infected with parasites, their skin will be damaged. Keepers need to put them in medicinal baths in yellow powder or potassium permanganate solution to avoid infection.
