If the big fish can't be raised well, raise another small fish. Tell me about it.

Fish farming is a technical activity, especially ornamental fish, which is difficult to raise well. It is not easy to form a balanced and stable ecosystem in a narrow and limited space. Water temperature, dissolved oxygen, illumination, filtration, ammonia nitrogen concentration, flora saturation and other factors are really not well coordinated. And understand the different habits of different fish. It's really not good to integrate these without some technology!

I hope the answer can help you, please adopt it!
