Pets are also sick as often as people, but because pets are sick, we may not know about them, which will cause damage to pets. We still often come into contact with pets living on land. Diseases can still be found in time, but we may not find fish pets in the water in time, so this requires us to have a certain understanding of the common diseases of fish pets we raise , Silver arowana is also a relatively common ornamental fish raised by everyone, so what common diseases do they have? How should we deal with these diseases?

Cat head lice: a disease caused by arthropod cat head lice parasitic fish feeding on fish blood. When the number is small, the parasites can be removed directly by hand and applied with antibiotic ointment. If the fish is young or the number of parasites is too large, the sick fish can be soaked in potassium permanganate solution of 1/80,000 for 1 hour, and the water temperature is 25-30 degrees Celsius once a day for a total of three times. Hyperthermia drugs can also be used.

Erythema: Also known as printing disease, it is a viral disease and can be said to be a terminal illness. Try raising the water temperature to 36 degrees Celsius and combining oral antibiotics with a medicated bath. I recommend trying Henamin.

Self-cutting disease: After the juvenile silver arowana is frightened, its dorsal, caudal, and anal fins are partially or completely broken off near the bottom of the body. The fractured surface generally does not bleed too much. Broken fins will grow back on their own. A certain amount of methyl blue can be added to prevent secondary infection. (The dosage is 10% of the usual dosage)

Spinal curvature: The symptom is that the spine of the arowana is curved into an S shape. It may be caused by improper use of drugs at the juvenile stage, poor water quality combined with insufficient transportation or malnutrition. Treatment is almost impossible, the key lies in prevention: keep the water clean, pay attention to balanced and adequate nutrition, try to prevent other fish diseases and try not to use drugs, put in the water pump to increase the amount of exercise of the arowana, and make the aquarium as large as possible.

Excessive fat: The reason is too much food and not enough exercise. Does not die but shortens lifespan and prevents spawning. Prevention: 1. Choose 1-2 days a week to stop eating. 2. Put in the water pumping motor or choose a few silver dragon fish to play with the fat fish to increase the amount of exercise.
