Black Angelfish can breed. When selecting species of fish, choose healthy, brightly colored and well-shaped small fish, and raise them from a young age. Regarding the issue of disability, it should be divided into two parts. Some disabilities should be resolutely avoided when selecting fish, such as: body tilt, deformation of head and mouth, etc.; but general trauma, broken scales and fins, etc., are Small problems will not affect the quality of reproduction.

Four issues should be paid attention to when raising black angelfish: It is better to change the amount of water less frequently; it can be controlled once every three days, 30% each time; its purpose is to stimulate the metabolic function of the fish. The second is to pay attention to preventing diseases and insects. Once the black angelfish becomes ill, it is not easy to treat. It is mainly a good medicine, and prevention should be the priority. The biggest diseases of black angelfish are internal worms and enteritis. After the new fish are stable, they should first be fed with bait to deworm the fish. The first time it is stable for 7-10 days, then once every two months, each time for three consecutive days, every day Once is enough.

Prevent enteritis with bait, once a month for two days. Small doses of medication will not affect reproduction. The third is to adhere to the diversity of bait, avoid singleness, and prevent malnutrition of breeding fish. The fourth is to avoid high temperature breeding, generally controlled at 25-26 ℃ as well, high temperature is not conducive to reproduction and the life of the fish. Once the species are raised, pairing is very easy, just let them pair naturally without being too demanding.
