Blue star fish can breed. For the reproduction of blue star fish, it is first necessary to select broodstock. Choosing the right broodstock is conducive to the success of subsequent breeding. There are many selection criteria. For example, the length should be more than 10 cm; for example, the age should be within one or two years; the appearance should also be good-looking, and the physique should be healthy.

Then is to prepare a suitable fish tank. The size of the fish tank needs to be determined according to the number of blue star fish breeding. In addition, some aquatic plants can be placed in the fish tank, which can be used by female fish to build their nests. Then, the water environment in the fish tank must also be paid attention to, and all aspects need to be regulated. The water temperature can be controlled between 26-28 degrees, not too low; the PH value of the water needs to be between 6.8-.2, and neutral water can be directly selected; the hardness is better controlled at 120-150ppm.

After that, you can put the selected blue star fish into the fish tank. The female fish will go to build a nest. After the nest is completed, the male will start chasing the female. Females will lay eggs in the nest, and males will fertilize.

After the females have spawned, they will look for a quiet place to rest. At this time, they can be directly fished out and placed in a separate tank to recuperate. Males can remain in the breeding tank, and they will protect the fertilized eggs, which will be released after they fall out of the nest. Keep the surrounding environment suitable, and the eggs will hatch successfully in about 3 days. Feeding can choose egg yolk.
