The seven-color angelfish can be considered to have grown up when they are raised to 10 to 14 months of age. Physiologically, after reaching sexual maturity, they can be considered adult fish. Under normal maintenance, the seven-color angelfish can reproduce at the age of 10 months, that is, spawning and fertilization, so it can be considered as an adult fish at this time.
However, they may not be very big at this time. When they are 14 months old, their size and physiology can reach the standard of adult fish, so it is generally believed that they can fully grow into adult fish at about 14 months old.
The body length of the seven-color angelfish generally does not exceed 20 centimeters, with an average of about 15 centimeters. How big it can grow depends on many factors, such as species, environment, feeding conditions and so on. Individual species, such as tiger dogs, may grow to 20 centimeters, which is affected by genes, but the general species of colorful angelfish, body length is about 15 centimeters. At the same time, if we can reasonably control the breeding density, properly supply oxygen, reasonably match the diet and ensure adequate nutrition, the body length of the cultured seven-color angelfish may also exceed 15 centimeters.
