1. Selection of parent fish: For breeding of blue star fish, the parent fish should be selected first. The selection of suitable parent fish is conducive to the success of subsequent reproduction. There are many criteria for selection. For example, the length, preferably more than 10 cm; For example, age, preferably in one or two years; The appearance must be good-looking, the physique must be healthy and so on.
2. Fish tank and water environment: Then prepare a suitable fish tank. The size of the fish tank depends on the number of blue star fish. In addition, some aquatic plants can be placed in the fish tank for female fish to build nests. Then, the water environment in the fish tank should 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 water needs to be between 6.8 and 0.2, and neutral water can be directly selected; And that hardness is preferably control between 120 and 150 ppm.
3. Nesting and spawning: After that, you can put the selected blue star fish into the fish tank. The female will go and build her nest. After the nesting is complete, the male chases the female. The female will lay eggs in the nest, and the male will fertilize them.
4. Incubation: After the female fish has laid eggs, they will find a quiet place to rest. At this time, they can be directly fished out and placed in a separate fish tank for recuperation. Males can remain in the breeding tank, where they protect the fertilized eggs and put them back 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.
The reproduction needs to pay attention to some skills, is helpful to the reproduction success. For example, when choosing parent fish, we must pay attention to age, although the blue star fish has reproductive capacity in six or seven months of breeding, but it is better to choose older fish, such as fish aged about one or two years, so that reproduction is easier to succeed. Moreover, whether the water temperature is suitable or not has a greater impact on the success rate of reproduction, so in the process of reproduction, we must always keep the water temperature suitable, not too low.
