CATDOLL : CATDOLL: How big can a parrot fish grow in a year?

There are too many uncertain factors, such as the size of the aquarium water area, water quality, water temperature, stocking density, quality of fish feed, etc. These are all objective factors that affect the growth of parrot fish.

My parrot fish was about 5 cm long when I bought it, and it grew to more than 20 cm after a year. Some of them grow very slowly, which may be due to congenital deficiencies. Those with a body length of 15 to 20 cm are considered adults.
