The rearing of parrotfish fry requires attention to the following aspects:
Water Temperature Control: Parrotfish fry have relatively high requirements for water temperature. The suitable water temperature should be maintained between 28°C and 29°C, and the water temperature should be kept constant. It is recommended to install a heating rod in the fish tank to regulate the water temperature.
Water Quality Management: It is very important to keep the water quality clean. Parrotfish fry have high requirements for water quality. It is recommended to change the water once every three days, and control the amount of water changed each time to one-third of the total water volume. If there is a filtration device in the fish tank, the frequency of water changes can be appropriately reduced.
Oxygen Supply: Parrotfish fry have a relatively high demand for oxygen. It is recommended to install an oxygen pump to ensure an adequate dissolved oxygen content in the water.
Diet Management: Parrotfish fry rely on egg yolk lecithin for nutrition in the first three days. After that, they can gradually be fed foods such as brine shrimp eggs, water fleas, and cooked egg yolks. When feeding, give small portions but multiple times to avoid the deterioration of water quality caused by food residues.
Environment Arrangement: Provide parrotfish fry with an appropriately sized water body space and an appropriate amount of shelters to offer a sense of security and a habitat. Keep the environment quiet to avoid disturbing the fry.
Health Observation: Closely observe the health status and appetite of the fry. When problems are found, promptly adjust the type of feed or the rearing environment.
By implementing the above measures, the healthy growth of parrotfish fry can be effectively promoted.
