Common name: Filament-finned parrotfish

General information

The Highfin Parrotfish, scientifically known as Scarus altipinnis, is a vibrant and colorful addition to any marine aquarium. This species is known for its striking appearance, with males exhibiting a bright green body and a characteristic high dorsal fin. Females and juveniles tend to have a more subdued coloration, often with a brownish base and scattered spots.

Parrotfish are named for their beak-like teeth, which they use to scrape algae and dead coral off of hard surfaces. This feeding behavior is crucial for the health of coral reefs as it helps prevent algal overgrowth and promotes coral growth.

Care

Highfin Parrotfish require a large tank with plenty of swimming space and rockwork to mimic their natural reef environment. They are active swimmers and can grow quite large, so a tank of at least several hundred gallons is recommended. They are herbivores, and their diet should consist of a variety of marine algae, vegetable matter, and high-quality commercial foods formulated for herbivorous fish.

Reproduction

In the wild, Scarus altipinnis exhibits protogynous hermaphroditism, where individuals start life as females and can change to males as they mature. This change is often triggered by social cues or the absence of a dominant male. In the aquarium, breeding Highfin Parrotfish is quite challenging and rarely achieved.

Habitat

Scarus altipinnis is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They are commonly seen in coral-rich areas and lagoons, usually at depths ranging from shallow waters to about 30 meters. They play a significant role in the ecosystem by maintaining the balance between coral and algae on the reefs.
