Angelfishes are a very popular tropical fish because of their unique shape and fascinating personalities. They adapt better in tall tanks rather than short tanks because of their body shape and have a wide variety of color mutations. During my younger years, only silver and marble types are commonly available.
Caring for angelfish has an intermediate level of difficulty. The aquarium should be warm, ideally around 80 degrees Fahrenheit (27 degrees Centigrade). As members of the cichlid family, they are generally peaceful.
They reach sexual maturity at around eight months of age. They have a lifespan longer than 10 years.
Three types of angelfish are Pterophyllum Altum, Leopoldi, and Scalare (the most popular).
