Common name: Blue-barred parrotfish

General information

The Blue-barred Parrotfish, Scarus ghobban, is a vibrant and dynamic addition to any large marine aquarium. Known for their remarkable ability to change colors and patterns throughout their life stages, these fish are a spectacle of the underwater world. Juveniles typically exhibit a different coloration compared to adults, with the latter showcasing striking blue bars against an orange backdrop.

Parrotfish are named for their beak-like dentition, which they use to scrape algae off hard surfaces, playing a crucial role in the health of coral reefs by preventing algal overgrowth.

Care

Blue-barred Parrotfish require spacious tanks with plenty of live rock to mimic their natural reef environment and to provide grazing opportunities. They are not suitable for small or reef tanks due to their size and feeding habits, which can disrupt coral and invertebrate life. A varied diet that includes algae and marine-based vegetable matter will help maintain their health and coloration.

Reproduction

In the wild, Scarus ghobban exhibits complex social structures and reproductive behaviors, including haremic groupings and sex change from female to male. While breeding in captivity is rare, understanding their natural spawning rituals can be fascinating for the dedicated hobbyist.

Habitat

Blue-barred Parrotfish are found in a variety of marine environments, from shallow lagoons to deeper coral reefs. They are widespread throughout the Indo-Pacific region, often seen grazing on algae-covered substrates.

Their role in bioerosion and sand production through the digestion of coral rock is a testament to their ecological importance, making them a species of interest not only to hobbyists but also to marine biologists.
