1. Reason: Silver arowana has higher requirements for water quality. The pH value of water should be kept between 6.5 and 7.5. Only in such water can they ensure the normal operation of their own life activities. If the water quality does not meet their growth requirements, it may cause them to sink to the bottom and not swim.
2. Solution: In this case, change the water for them. The pH value of the water is ensured to be between 6.5 and 7.5, and the content of nitrite in the water is ensured to be reduced to 0. Don't change too much water at one time, or it will cause them to have a stress reaction. It can be changed about a quarter at a time, and it can be changed in 3-4 times. Water trapping should be carried out before each water change.
1. Reason: Only by providing suitable lighting for silver arowana can they maintain vigorous vitality. If they lack light for a long time, they will be listless and even sink to the bottom.
2. How to deal with it: In this case, they should be given additional light. Provide 8-10 hours of light during the day. The light should not be too strong, but should be soft, so as not to burn them. If there is no light in the fish tank, you can use aquarium lights to supplement their light.
1, the reason: to feed the silver arowana regularly and quantitatively, can not feed too much food at one time. If too much food is fed, it may cause them to eat too much, which will lead to the problem of sinking to the bottom and not swimming.
2. Treatment method: First, temporarily stop eating for a period of time, and properly enhance the water flow in the tank to promote their swimming and digestion of food. After that, the feeding should be regular and quantitative, and the feeding amount of each meal should be well controlled, so that they can eat 7-8 minutes full.
