1. Selection of broodstock: The broodstock selected must be strong, with fully mature gonads, and the female and male broodstock used must be in heat at the same time. The broodstock must have the characteristics of the species, and the female and male broodstock should normally appear affectionate with each other. Avoid selecting tropical fish from the same brood or with close blood relations as broodstock, to prevent inbreeding from causing degeneration in the quality of the offspring. Tropical fish with torn fins, disabilities, or deformities should not be used as broodstock. 2. Preparation of the breeding tank: Because broodstock species differ, the breeding tank also differs. Generally, for tropical fish that lay floating eggs

1. Selection of broodstock: The broodstock selected must be strong, with fully mature gonads, and the female and male broodstock used must be in heat at the same time.

Avoid selecting tropical fish from the same brood or with close blood relations as broodstock, to prevent inbreeding from causing degeneration in the quality of the offspring. Tropical fish with torn fins, disabilities, or deformities should not be used as broodstock.

2. Preparation of the breeding tank: Because broodstock species differ, the breeding tank also differs. Generally, use a larger breeding tank for tropical fish that lay floating eggs, and a smaller tank for those that lay demersal eggs. For tropical fish with no strict water quality requirements, an ordinary fish tank can be used; for those with strict water quality requirements, a glass fish tank should be used. Before use, clean and disinfect the fish tank, adjust the water according to the water quality and water temperature required for the breeding of the various tropical fish, and pour it into the tank, with the water height accounting for 1/3-1/2 of the height of the breeding tank. Place sand, aquatic plants, stones, etc. at the bottom of the tank, but do not put in snails or cyclops.

3. Hatching of fish eggs: Water temperature, water quality, hardness, dissolved oxygen, pH, and light all affect the hatching of fish eggs. Fertilized fish eggs begin to divide from the animal pole, passing through the cleavage stage, morula stage, blastula stage, gastrula stage, embryo maturation stage, and hatching stage, and finally hatch into fry.

4. Feeding of fry: Newly hatched fry use the yolk sac for nutrition, and once they can swim freely, they begin to feed. Feed the fry paramecia, then rotifers, and finally screened water fleas. If the water does not deteriorate, there is no need to change the water; when water needs to be changed, add new water not exceeding 1/10 of the original water volume. The fry tank should be placed in a place with a constant temperature as much as possible. As the fry grow, they should be raised in separate tanks according to size. The fish tank used for feeding fry must not be contaminated with the larvae of Hydra and water fleas - the water centipede.
