To make parrot fish grow rapidly, the key lies in providing a suitable environment and reasonable feeding management.
Firstly, parrot fish are omnivorous fish and can eat artificial bait, bloodworms, brine shrimp and so on. To promote the growth of parrot fish, it is recommended to regularly feed them with live small fish and shrimp, and add astaxanthin and carotenoids to the feed. These substances can help maintain the vivid body color of parrot fish.
Secondly, parrot fish are suitable for growing in soft water, and the water quality should be kept clean. If the water becomes cloudy, the water should be changed in a timely manner to keep it fresh. Besides, parrot fish have a relatively strong adaptability to temperature, but changes in water temperature have a significant impact on their body color and health. It is recommended to control the water temperature between 25℃ and 28℃ to avoid the drastic changes in water temperature affecting the growth and body color of parrot fish.
Finally, the growth rate of parrot fish is especially crucial in the first five months. During the fry stage, brine shrimp larvae can be used for feeding. As the fish grow larger, the diet can gradually shift to water fleas, adult brine shrimp, red thread worms, black shell shrimp and other foods. When feeding, the principle of feeding small amounts but frequently should be followed to ensure that each fish can get enough food. Meanwhile, keep the density in the fish tank at a moderate level, and the frequency of water changes should be adjusted appropriately according to the feeding frequency to promote the healthy growth of parrot fish.
