Deirdre Paige –
This parrotfish has been in my 150-gallon reef tank for over a year. It’s active but calm, and doesn’t bother the corals. Only feeding once a day with a mix of algae wafers and spirulina. Very satisfied with the peaceful nature and appearance.
Peter Tucker –
Grew from 3.5″ to 4″ in six months. Needs a large tank and expert care. Feeding is essential. No issues with other fish or corals so far. A good choice for experienced reef keepers.

Installed in a mature reef system. It’s clean and doesn’t cause any disturbances. The coloration is vibrant and it’s a great addition to the tank. Only requires daily feeding and regular water testing.
