I raised 30 guppies in hydroponic plants. Can I live without oxygen?

Hydroponics can really play a big role. Generally, nitrifying bacteria should be raised first in fish farming, but the straw tank can completely reduce the content of nitrifying bacteria, achieve the substitution effect, and still keep the water clean.

Besides, a lot of aquatic plants can do it. For example, a fish tank with 12 liter can generally raise more than 10 fish under 5 cm, while a straw tank can raise more than 5 fish. In addition, grass needs enough photosynthesis to be raised well. Without photosynthesis, oxygen will not be released. When plants die, the water quality will deteriorate and fish will die.

-In short, you can raise 10 haypots, and 15 haypots doesn't matter. Article 20 when you are sick, you may be prone to problems. It's okay to raise well.
