The parrot fish should be a reef fish, that is, a coral fish. Because benthic microalgae in reef rocks from 35 north latitude to 35 south latitude may contain a highly toxic toxin called ciguatoxin, marine fish that eat these algae for a long time may also accumulate toxins in their bodies. So it is better to eat less. If you must eat, avoid eating fish heads, internal organs, fish skins, fish eggs and other parts where toxins are concentrated. If you have typical poisoning symptoms such as tingling, vomiting and diarrhea on your face, neck and mouth, you should go to the hospital as soon as possible.
