of water quality 1. Reason: Silver arowana is very sensitive to water quality. If the water in the aquaculture tank suddenly changes, such as PH value changes, water temperature changes, etc., it is easy to cause silver arowana to lie at the bottom of the tank.
2. Treatment method: In this case, first of all, determine where the water quality has changed. If the PH value has changed, change the water immediately. If the water temperature changes suddenly, it is necessary to immediately restore the water temperature to the range suitable for the life of silver arowana, preferably at about 28 degrees.
of environment 1. Reason: Silver arowana is very timid. If the surrounding environment suddenly changes, it will make a defensive posture, that is, lying low in the tank.
2. Treatment: Try to minimize the disturbance to the silver arowana, except for feeding and changing water, do not disturb it at this stage. When the silver arowana is sure that there is no danger around it and adapts to the new environment, the situation of lying at the bottom of the tank will gradually ease.
1. Reason: If there is a sudden abnormal noise around or a scene that has not been seen before, the arowana will also be frightened to lie low in the tank.
2. Treatment method: At this time, it is necessary to eliminate the abnormal noise around and keep the maintenance environment as stable as possible. Usually after two or three days, the arowana will put down its guard and start its activities.
