Overview
- Native to the Indo-Pacific, frequently found in coral reefs, lagoons, and rocky reef formations.
- Recognized for its striking coloration that changes as it matures, from a bright orange juvenile stage to a mix of blue, green, and pink as an adult.
- Known for its beak-like mouth, which is used to scrape algae off rocks and coral.
- Can grow to a substantial size and requires a large tank with ample space for swimming.
- Best suited for an established marine aquarium with plenty of live rock for grazing.
Feeding
- Herbivorous, primarily feeding on algae and coral polyps in the wild.
- Accepts marine algae sheets, spirulina-based pellets, and fresh seaweed in captivity.
- Providing a varied plant-based diet supports healthy growth and vibrant coloration.
- Requires frequent feedings to meet its dietary needs and maintain its energy levels.
- May consume live rock over time, contributing to bioerosion in reef environments.
Habitat
- Typically found in reef environments with an abundance of live rock for grazing.
- Prefers stable water conditions with moderate to strong water flow.
- Aquarium setups should include large rock structures and open swimming areas.
- Requires a well-maintained marine tank with high-quality filtration due to its high metabolism.
- Providing an enriched environment encourages natural behaviors and reduces stress.
Fish Care
- Optimal water temperature: 74-80°F (23-27°C) to support metabolic function.
- Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
- Requires strong filtration and routine water changes to maintain water clarity.
- Needs an aquarium large enough to accommodate its size and grazing habits.
- Providing live rock formations enhances its environment and supports natural feeding behaviors.
Compatibility
- Generally peaceful but requires tankmates that can tolerate its constant movement and grazing.
- Compatible with tangs, wrasses, and other herbivorous or semi-aggressive fish.
- Not entirely reef-safe, as it may damage corals while feeding on algae.
- Should not be housed with highly aggressive species that may stress it.
- Providing ample swimming space and hiding spots helps minimize territorial disputes.
Aquarium Behavior
- A highly active swimmer that constantly explores its environment.
- Often observed scraping algae off rocks and occasionally biting at tank surfaces.
- Can exhibit territorial behavior towards other herbivorous fish if space is limited.
- Providing live rock structures and varied tank decor supports natural grazing habits.
- Over time, it may become more interactive with its caretaker, particularly around feeding times.
