Pearlscale Angelfish

Pearlscale Angelfish, scientifically named Centropyge vroliki, is also known as the Half Black Angelfish.

This marine fish has ray-like fins and belongs to the Pomacanthidae family of angelfish. It can be found in the Indo-Pacific region.

Pearlscale angelfish lives in lagoons and seaward reefs, mainly in coral-rich areas. It feeds on algae and reproduces by laying eggs.

This fish is monogamous, meaning it has only one mate.

Pearlscale angelfish is frequently exported for the aquarium trade and forms hybrids with Centropyge eibli and Centropyge flavissima in areas where their habitats overlap.

Young ones of the Acanthurus pyroferus fish mimic the pearlscale angelfish.

When keeping this fish in a reef tank, approach with caution because it may pose a risk to the coral reefs in an aquarium environment.
