General information

The Redtail Parrotfish, also known as the Stoplight Parrotfish, is a colorful and dynamic addition to any large marine aquarium. This species is known for its remarkable ability to change colors and patterns as it matures, with juveniles displaying a completely different appearance from adults. The Redtail Parrotfish is a bioeroder, meaning it plays a crucial role in the reef ecosystem by grazing on algae and dead coral, which helps to prevent algal overgrowth and maintain the health of coral reefs.

Care

Sparisoma chrysopterum requires a spacious aquarium with plenty of live rock for grazing and hiding. They are not suitable for reef aquariums as they have a tendency to nip at and consume stony and soft corals, as well as clams. A varied diet that includes algae, marine-based plant matter, and occasional meaty foods will help maintain their health and vibrant coloration.

Reproduction

In the wild, Redtail Parrotfish are protogynous hermaphrodites, starting life as females and potentially changing to males as they mature. They exhibit complex mating behaviors and are not commonly bred in captivity due to their size and social dynamics.

Habitat

Native to the Western Atlantic, from Florida and the Bahamas to Brazil, the Redtail Parrotfish is commonly found in shallow, coral-rich areas and seagrass beds. They are often observed grazing in small groups and can be found at depths ranging from 3 to 25 meters.
