Do not let fish hypoxia, in addition to oxygen pumps and plants, what else?
The fish tank is a bit bigger. It's bigger
My family also raises fish, as if only those two methods
You simply build a small fish pond, and want to make up the oxygen, only those two methods, and then higher point estimate in the future will appear...... Can you get some weed and mud in the river? Isn't it convenient? I keep it that way
