Growth speed varies by variety; with good care some blood parrot fish reach 20 cm in about a year. But some small types are naturally short and may never reach 20 cm. Nutrition strongly affects growth; poor nutrition slows it, possibly taking two years.
Therefore feed scientifically with enough nutrition and keep the environment clean for normal growth.
