Common name: Common parrotfish

General information

The Queen Parrotfish, Scarus psittacus, is a vibrant and colorful species known for its parrot-like beak, which is used to scrape algae from coral and rocks. This beak is actually made up of numerous small teeth fused together. As a member of the Scaridae family, it plays a crucial role in maintaining the health of coral reefs by controlling algae growth and contributing to the bioerosion process that creates sand.

Juveniles exhibit different coloration compared to adults, and the species is known for its ability to change sex from female to male during its life cycle, a phenomenon known as sequential hermaphroditism.

Care

Queen Parrotfish require large, mature aquariums with plenty of live rock to graze on and open swimming space. They are not recommended for reef aquariums as they can cause significant damage to coral structures. A varied diet that includes algae and marine-based plant matter is essential for their well-being.

Reproduction

In the wild, Queen Parrotfish are protogynous hermaphrodites, starting life as females and potentially changing to males as they mature. They engage in spawning aggregations where fertilization occurs externally. Replicating these conditions in captivity is challenging and rarely achieved.

Habitat

Scarus psittacus is found in tropical and subtropical waters of the Western Atlantic, from Florida and the Bahamas to Brazil. They inhabit coral reefs, especially spur and groove formations, and are often seen grazing in shallow waters.
