Common name: Bicolor parrotfish

Scientific name: Cetoscarus bicolor (Rüppell, 1829)

General information

The Bicolor Parrotfish, scientifically known as Cetoscarus bicolor, is a vibrant and distinctive species popular among aquarists for its striking coloration and unique beak-like teeth. Juveniles exhibit a different color pattern compared to adults, with the former displaying a white body with an orange band, while adults have a greenish-blue body with pinkish or yellowish scales, and a characteristic hump on the head.

Care

Caring for Bicolor Parrotfish requires a spacious tank due to their size and active swimming behavior. They are herbivorous, feeding primarily on algae, and their beak-like teeth are adapted to scrape off algae from hard surfaces. It's essential to provide a diet rich in vegetable matter and to maintain high water quality.

Reproduction

In the wild, Bicolor Parrotfish are protogynous hermaphrodites, meaning they start life as females and can change to males as they mature. They exhibit complex social and mating behaviors, often forming harems with a dominant male.

Symbiosis

While not known for specific symbiotic relationships like clownfish and anemones, Bicolor Parrotfish play a crucial role in the ecosystem by grazing on algae, which helps prevent overgrowth and maintain coral health.

Habitat

Bicolor Parrotfish are found in tropical and subtropical reefs across the Indo-Pacific region. They prefer coral-rich areas and are often seen grazing on algae-covered surfaces. Their presence is vital for the health of the reef as they help control algae growth.
