Fortune-telling fish head down _ fish head down means

What's with my head facing downstream?

The fish head facing downstream may be due to lack of oxygen or bacterial infection. Lack of oxygen will lead to the infection of floating objects in fish, which will make the fish unable to maintain balance. In addition, bacterial infection can also lead to fish imbalance. It is suggested to replace the fish tank water in time and add appropriate amount of salt for disinfection. If the situation is serious, consider adding an appropriate amount of anti-inflammatory drugs.

I hope the above suggestions can help you. If the problem still exists, I suggest you consult an aquarium expert or seek professional help.
