1. Environment: To raise octopus, it is necessary to prepare a comfortable environment according to their habits. The first is the living space. You can choose the size of the fish tank according to the size of the octopus. Besides size, pay attention to depth. Octopus in a shallow fish tank may climb out directly. Secondly, the aquaculture water should choose seawater, because octopus is a marine organism and is used to living in seawater, so the salt content in water is best at 1.201. Finally, a layer of gravel and ceramic tanks should be laid in the fish tank, which can restore the marine environment more.

2. Water temperature: Octopus does not require high water temperature, and they can live in water temperature between 15-32 ℃. If the aquaculture water temperature is lower than 15 ℃, it is necessary to install a heating rod to keep the water temperature in a stable range.

3. Oxygen: Octopus has a large demand for oxygen. If the breeding space is not very large, it is best to keep oxygenation, so as to ensure sufficient dissolved oxygen in water.

Octopus likes to eat some shrimps, shellfish and crabs best, and can choose to feed some shrimps in artificial culture. Octopus is clever, and the food fed does not need to be handled deliberately, but can be put directly into water. Like shrimp, they swallow it directly, but shellfish and crabs, they bite the outer shell of food and eat the meat inside. Therefore, when culturing octopus artificially, it is enough to put food directly into water.
