Genus
Common name: Roa Butterflyfish
Scientific name: Roa
Roa is a genus of butterflyfish known for their striking coloration and patterns, which make them popular in the reefkeeping hobby. They are typically found in the Indo-Pacific region and are known for their peaceful temperament, making them suitable for community tanks. Roa species are omnivores, feeding on a variety of foods including algae, coral polyps, and small invertebrates. They require a well-established aquarium with plenty of hiding places and live rock for grazing. It's important to note that some species may nip at coral, so they should be monitored in a reef tank setting.
