parrot fish suitable for family feeding? It is more appropriate to control the water depth at 30-50cm. The height of the fish tank shall be more than 60 cm. If the filtration and circulation system are strong, a smaller fish tank is also possible. If the parrot fish is young, the water level can be lowered a little. Because the higher the water level, the less oxygen there is at the bottom of the tank. Parrot fish's lips are congenitally unable to close, and small fish need more oxygen than large fish, so when parrot fish are born, the water level is recommended to be kept at about 30 cm.
parrot fish can be calculated by the length of the fish tank * the width of the fish tank * the height of the water level/the average body length of the fish, which is a generally recognized algorithm. For example, a fish tank with a length of 1 meter, a width of 0.3 meters and a height of 60 meters can raise about 15 cm long parrot fish, which is 10 * 3 * 6/15 = 12. The number of 20cm long parrot fish is 10 * 3 * 6/20 = 9. Some people calculate by one centimeter and one liter of water, which is also recognized as a relatively simple and convenient method. For example, a fish tank with a volume of 500 liters can raise about 25 parrot fish with a length of 20 cm. Under the condition of ensuring the good function of the filtration system, the number of fish can be increased appropriately. But if the filtration system is less functional, or there is no filtration system, then reduce the number of fish.
