1. Hit the tank 1. Reason: When the red arowana is fed too little or the surrounding environment changes greatly, they will constantly hit the fish tank, and the scales on their bodies will fall off.
2. Treatment method: First, put food into the red arowana according to the number of them in the fish tank, and strive for every red arowana to be full. Then make sure the surrounding environment of the red arowana is quiet, and don't walk around the fish tank at this time.
2. Diseases1. Reason: When red arowana is infected with diseases such as water mold, the functions of various organs of their bodies will decline, and the scales on their bodies will fall off continuously.
2. Treatment: Fish out sick red arowana and keep them in a fish tank to prevent them from infecting other healthy fish. Then choose a fish tank and put a low concentration potassium permanganate solution. Finally, put the diseased fish in potassium permanganate solution and soak them for 20-30 minutes every day until they recover.
3. The water quality is too poor1. Reason: When the water quality in the fish tank is too poor, the germs in the water will multiply in large numbers, not only the red arowana competes for oxygen and minerals in the water, but also produces some harmful gases. At this time, it will cause the silver arowana to drop scales.
2. Treatment method: First, replace a part of the water in the fish tank to adjust the water quality. Then add some nitrifying bacteria to the water, and the nitrifying bacteria will remove some harmful gases from the water.
