Symptoms:	The skin will exhibit red inflamed spots on which secondary bacterial infections can occur. The fish swims irregularly and show signs of restlessness.
Treatments:	If the fish louse doesn't occur in large numbers, they can be controlled by simply removing them carefully with a pair of tweezers. Use Trichlorfon in cases of mass infection, but be careful not to poison the fish (Dose: 0.25 –3.0 mg/1 liter water for 3 days. The dosage depends on the hardness of the water, the harder the water the more trichlorfon can be used. A 35% water change is recommended after treatment or carbon filter can be used). Formalin also has good results (Dose: 0.1 ml liter of aquarium water for 30-45 minutes. Also 1.0-1.5 ml/100 l for 2 days).
