Octopuses can be kept as pets. However, due to the special living habits of octopuses and the difficulty of breeding, it is necessary to consider carefully before deciding whether to raise them.
Octopus is a general term for octopod octopod cephalopod mollusks, their bodies are short oval, sac-shaped, finless, the head and body are not clearly divided, and they have large compound eyes and 8 retractable wrists on their heads.
Octopuses have highly developed pigment-containing cells that change body color very quickly.
Octopuses are very adaptable and reproduce at a sea temperature of around 16, with a specific gravity of 1021 is the most suitable, and it will die in a low salinity environment. They are carnivores and feed on gills and crustaceans (shrimp, crabs, etc.), and some species can also feed on large zooplankton. And it is widely distributed in the tropical and temperate seas of the world's oceans.
Octopuses also have well-developed eyes, three hearts, and two memory systems, and can constantly change their behavior, as well as their color and structure.
If you want to raise octopus, first of all, you need to prepare a comfortable living environment for the octopus.
You can choose a moderately sized fish tank, taking care that the depth is sufficient to prevent the octopus from escaping. At the same time, in order to simulate the marine environment, a layer of gravel can be laid on the bottom of the fish tank, and some ceramic jars or conch shells can be added for the octopus to hide.
The salinity of the sea water where the octopus lives should be 1021, so it is necessary to use special seawater or salt water in a certain proportion. At the same time, the water quality needs to be changed regularly to keep the water clean and stable.
Octopuses have high water temperature requirements, generally between 15-23. Therefore, equipment such as heating rods is required to keep the water temperature stable. In the summer when the temperature is high, it is also necessary to pay attention to cooling down to prevent the octopus from being overheated.
Octopuses are carnivorous animals that feed mainly on other marine life. In captivity, you can choose a feed specially designed for octopus, or provide fresh seafood such as shrimp, small fish, etc.
Octopuses sometimes spray ink to evade enemies or as a defense mechanism, but ink is poisonous, so the tank needs to be cleaned and the water changed in time.
