Different kinds of starfish have different requirements for water temperature and PH value. First of all, you must buy an aquarium that can adjust the water temperature, adjust the water temperature and PH value according to the type of starfish, and place small fish, shrimp and other marine plants and animals that can **** with it, but can not be raised with freshwater fish.
Some starfish are carnivorous and some are omnivorous. The food is dried seaweed, clam meat or pieces of meat, which can be placed near or under the body of the starfish when feeding.
The main predators are slow-moving marine animals such as shellfish, sea urchins, crabs and sea anemones. It often adopts a slow, meandering strategy, approaching its prey slowly, catching it with its tube feet on its wrists and wrapping its entire body around it, spitting the stomach pouch out of its mouth, and using digestive enzymes to dissolve the prey outside its body and absorb it.
