General information

The Obishime Parrotfish, Scarus obishime, is a vibrant and colorful addition to the marine aquarium. This species is known for its striking coloration and the ability to change colors and patterns as it matures. Parrotfish are named for their beak-like teeth, which they use to scrape algae from coral and rocks, playing a crucial role in the health of coral reefs.

Care

Scarus obishime requires a large aquarium with plenty of swimming space and live rock for grazing. They are active swimmers and can grow to a considerable size, so a tank of at least 500 liters is recommended. These fish are herbivores, and their diet should consist of high-quality marine algae, vegetable matter, and prepared foods that promote their vibrant coloration.

Reproduction

Parrotfish are protogynous hermaphrodites, meaning they are born female and have the potential to change to male later in life. In the wild, this change is often triggered by social cues or the absence of a dominant male. Breeding in captivity is rare and challenging due to their complex social structures and spawning behaviors.

Habitat

The Obishime Parrotfish is found in the Western Pacific, particularly around Japan. They inhabit coral reefs and are often seen grazing on the reef's surface. In the aquarium, they require a simulated reef environment with a strong current and high water quality to thrive.
