Cetoscarus bicolor – Bicolor Parrotfish with Copper Band

The Cetoscarus bicolor, also known as the red-spotted parrotfish, is a splendid reef fish with a elongated white body, enhanced by a distinctive copper band running across the back of its head. Its juvenile appearance is elegant, and it undergoes a spectacular metamorphosis as it ages, drastically changing coloration like all parrotfish of its kind.

A Spectacular Fast-Growing Fish

Native to the Indo-Pacific, the Cetoscarus bicolor is a robust species that requires a very large reef aquarium. It is best to provide it with a space of at least 800 liters with large free swimming areas and a decor rich in rocks. It actively contributes to sand stirring and ecosystem balance by feeding on microalgae and biofilms present on hard surfaces.

Maintenance Conditions

• Recommended Minimum Volume: 800 liters
• Temperature: 24°C to 27°C
• pH: 8.0 to 8.4
• Decor: live rocks, sandy substrate, open areas
• Water Flow: moderate to strong

Behavior and Compatibility

Generally peaceful in nature, this fish can become territorial once adult. It should be kept alone or in pairs, avoiding cohabitation with other parrotfish. Its behavior is compatible with robust invertebrates, but it is not recommended in tanks with fragile corals, as it may nibble on calcareous substrates.

Diet

• Fresh and dried algae
• Enriched vegetable pellets
• Spinach, nori, brine shrimp, and mysis as supplements

The Cetoscarus bicolor is a majestic and unique fish suited for experienced aquarists with an XXL aquarium. It quickly becomes the centerpiece of the tank thanks to its noble appearance, calm behavior, and beneficial ecological role.
