Octopus is better to feed, because they don't have high requirements for the environment. When artificially cultured, they can live normally as long as they pay attention to water quality and food. In addition, their adaptability is relatively strong, so if they know their habits well in artificial breeding, they can feed octopus.

1. The depth is enough: octopus has certain climbing ability, so we should pay attention to the depth of container when raising octopus. The specific depth of the fish tank can be determined according to the size of the octopus. If you can't prepare a deeper fish tank, you can add a lid to the fish tank to prevent octopus from escaping.

2. Adequate oxygen: Octopus has a high demand for oxygen, so it is best to continue a small amount of oxygen supply during artificial breeding, so as to ensure their sufficient oxygen. If octopus has insufficient living space, it needs a lot of oxygen to ensure sufficient dissolved oxygen in water.

3. Suitable water quality: Octopus belongs to marine life, so pay attention not to use fresh water when culturing artificially. If there is no seawater, you can add some sea salt or seawater essence to fresh water to simulate natural seawater.

4. Stable temperature: When octopus lives on the seabed, the temperature fluctuation will not be too large, and attention should be paid to the fluctuation of water temperature when cultured artificially.
