Common name: Eclipse parrotfish

General information

The Blueside Parrotfish, scientifically known as Scarus russelii, is a vibrant and active member of the reef community. This species is known for its striking coloration, which includes various shades of blue, green, and yellow, with males typically exhibiting more vivid hues than females. As a member of the Scaridae family, it plays a crucial role in the ecosystem by grazing on algae, which helps prevent overgrowth and maintain the health of coral reefs.

Care

Caring for Blueside Parrotfish requires a spacious aquarium with plenty of live rock to simulate their natural habitat and provide grazing opportunities. They are known for their robust appetite and can be quite destructive to corals and invertebrates, making them more suitable for fish-only or larger reef systems where their feeding habits can be accommodated. A varied diet that includes algae-based foods and occasional meaty offerings will help maintain their health and coloration.

Reproduction

In the wild, Blueside Parrotfish are protogynous hermaphrodites, meaning they are born female and have the ability to change to male later in life. This change is often triggered by social or environmental factors. In the aquarium setting, breeding these fish is quite challenging due to their complex life cycle and social dynamics.

Habitat

Scarus russelii is commonly found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often seen grazing on algae-covered surfaces. They are a benthic species, meaning they live and feed near the bottom of their environment.
