Angelfish generally can grow to about 12 - 18 centimeters. The body length of adult angelfish usually falls within this range. Under captive breeding conditions, they can generally grow to about 15 centimeters. Some experienced hobbyists can even get their angelfish to grow to 20 centimeters, and in extremely rare cases, they can reach 30 centimeters.
The growth of angelfish is not only influenced by innate genes but also closely related to the postnatal breeding environment. Correct breeding methods include keeping the water clean, changing the water regularly, cleaning the filtration system, providing appropriate bait, and controlling the temperature. All these contribute to the healthy growth of angelfish. Additionally, the lifespan of angelfish is generally 4 - 5 years. In the wild, they can live up to about 10 years, while those in artificial breeding may have a shorter lifespan due to factors such as inbreeding.
Because of their beautiful appearance and gentle temperament, angelfish have become the top choice among tropical fish and are hailed as the "Queen of Tropical Fish." They are mainly distributed in freshwater environments in tropical and subtropical regions. They are highly adaptable and have relatively low requirements for water quality, making them suitable for home aquariums.
