with the white floccule on the body of the red arowana? If the white floccule on the body of the red arowana, you need to immediately change the water to warm up, and at the same time inject penicillin into the tank for treatment. This kind of disease is generally Saprolegniasis, which is a common fish disease. There are many pathogens, not just Saprolegniasis. The bacteria invade from the wound of the fish and then grow hyphae, so when they are found, they are often more serious and need immediate treatment. It usually takes three to four days to recover.
1. Fish injuries: As mentioned above, pathogenic fungi can invade from the wounds of fish, so the disease is usually caused by fish injuries. This kind of fish is rarely mixed, and its size is large, few fish can hurt it, so it is usually caused by rubbing the tank or sharp objects in the tank. At ordinary times, we must observe more to see if there are any wounds, if so, immediately disinfect them.
2. Poor water quality: In addition to injuries, poor water quality is also an important factor leading to the disease of fish. The water has not been changed for a long time, or the fish tank has not been disinfected before introducing new things, thus carrying germs into it. Therefore, water should be changed regularly, and any objects entering the fish tank should be disinfected in advance.
3. Low temperature: Saprolegniasis is easy to suffer from in low temperature season, and high temperature can have a certain preventive effect. And the arowana itself is a tropical fish, so it needs to maintain a slightly higher water temperature, usually between 24-28 degrees Celsius, so as to prevent it from getting sick.
