Common name: Yellowbar parrot

General information

The Zonarchus Parrotfish, scientifically known as Calotomus zonarchus, is a vibrant and active member of the reef community. This species is known for its striking coloration and the unique ability to change colors and patterns as it matures. Juveniles typically exhibit a different color palette compared to adults, which can make them a fascinating subject for observation in a home aquarium.

Care

Caring for Zonarchus Parrotfish requires a spacious tank with plenty of live rock for grazing and hiding. They are herbivorous and need a diet rich in algae and vegetable matter to thrive. It's important to maintain high water quality and stable parameters to keep these fish healthy. They can be territorial, so it's advisable to introduce them to the aquarium last to minimize aggression.

Reproduction

In the wild, Zonarchus Parrotfish are protogynous hermaphrodites, meaning they start life as females and can change to males later on. Breeding them in captivity is challenging and rarely achieved by hobbyists due to their complex social and environmental needs.

Habitat

Zonarchus Parrotfish are found in the Indo-Pacific region, from East Africa to the Line Islands, north to southern Japan, and south to the Great Barrier Reef. They inhabit coral reefs and rocky areas, often seen grazing on algae in shallow waters.
