Parrotfish can be fed once or twice a day, and the specific frequency can be adjusted according to the actual situation. If possible, they can be fed once or twice a day, usually once in the morning and once in the afternoon.
Parrotfish are carnivorous fish and mainly feed on small benthic animals, including seaweeds, corals and sea urchins. Some of their food is poisonous, but parrotfish have organs in their bodies that can break down and digest toxins, so they won't be harmed by the toxins.
Parrotfish inhabit the mixed areas of reefs and sands in tropical and subtropical oceans. They mainly live at a depth of 30 to 50 centimeters below the water surface. They are united and helpful to each other. Once a companion is in danger, other fish will rush to help without hesitation. Besides, at night, parrotfish will burrow into the sand to sleep. They secrete mucus to form a thin film covering their whole bodies and dissolve it cleanly when day breaks.
