of environment 1. Reason: Silver arowana is very sensitive to the maintenance environment, and sometimes a little change will frighten them. When the silver arowana is frightened, it will lie at the bottom of the tank.
2. Treatment method: Before the silver arowana has not adapted to the new environment, the silver arowana can not be forced to drive. The environment should be kept as stable as possible to avoid large abnormal noises. In a week or so, the silver arowana can adapt to the new environment and improve the situation at the bottom of the tank.
1, reason: Summer is more sultry, the anoxic circumstance appears easily inside the aquarium that breeds silver dragon. Silver dragons do not like to swim if they lack oxygen, and they will sink at the bottom of the jar.
2. Treatment method: At this time, it is necessary to immediately add oxygen to the fish tank, and use an oxygen pump to pump oxygen.
of water quality 1. Reason: If the water quality of the cultured silver arowana changes suddenly, such as water temperature changes, PH value changes, etc., it will cause the silver arowana to sink to the bottom of the tank.
2. Treatment method: First determine the reason for the change of water quality, and then solve the problem. If the PH value changes, it is necessary to change the water for the silver arowana immediately. If the water temperature changes suddenly, it is necessary to adjust the water temperature and control the water temperature at about 28 degrees. In winter, the water temperature is easy to drop to the bottom, so a heating rod can be placed in the fish tank to control the water temperature.
