1. Cause: The cause of skin congestive disease in silver arowana may be too little light, which is common in rainy weather. It may also be due to sudden changes in water quality, such as too much water exchange or too much temperature difference, which can stimulate arowana, which usually occurs in the season with changeable temperatures.
2. Treatment: The breeder can first provide them with sufficient light, then dissolve 0.2 grams of furacilin powder and 250 ppm of salt in water, and give the silver arowana a medicinal bath for 10-20 minutes each time, or directly sprinkle it in the fish tank. Medicated bath several times, the red color can fade. You can also put the arowana into a low-concentration potassium permanganate solution for 10 hours and stick to it three times, which will be effective.
feeding 1. Reason: If the silver arowana is not fed properly when it is young, it will turn red. For example, if it is often fed with some shrimps or red feed, the silver arowana will turn red. Or sudden changes in water quality or environment will also turn red. This condition does not affect the health of the silver arowana, and it will turn silver as an adult.
2. Treatment: The breeder can wait for the silver arowana to recover by itself after it becomes an adult, or stop feeding the hyperchromic feed, and the feeding amount of shrimp should also be reduced. In this way, the silver arowana will slowly return to silver.
