1. Environmental problems: fish living in turbid water environment, hydrogen content is too high, the temperature is not within the appropriate range, will cause arowana conjunctiva.
2. Eye disease: TB and other bacterial growth. The eyes of arowana are infected by bacteria, and white membrane will appear when it is serious.
1. Change the water: If it is because of poor water quality, the problem is not particularly serious, you can not use drug treatment. There are two kinds of water quality problems. One is caused by hydrogen in the water entering the eyes of arowana. Second, the long-term non-replacement of water leads to the deterioration of water quality and destroys the normal living environment of fish. For the above two cases, as long as one third of the old water in the water tank is replaced every day, new water is added and appropriate salt is added to adjust it. Note that the temperature of the new water should be roughly the same as that of the old water, so as to avoid excessive temperature difference causing discomfort to the fish.
2. Medication: If it is caused by bacterial infection, bactericidal or antibiotic drugs can be used for treatment. Attention should be paid to the selection of special drugs for fish. When spraying the medicine into the water tank, the water temperature should be increased by 2 to 3 deg C to fully dissolve the medicine. In the process of medication, it is necessary to avoid drug residues leading to poor water quality and secondary infection. If the condition of the fish is improved, the dosage should be reduced.
