General Description

The Purple Masked Angelfish, also known as Venustus Angel or Blue-backed Angelfish, displays a striking contrast of blue and yellow coloring, making it a visually appealing addition to any aquarium setting. This species, scientifically named Paracentropyge venusta, can grow up to 12.7 cm in size.

Aquarium Suitability

The Purple Masked Angelfish is recommended for expert aquarists due to its specific care requirements. It is suitable for a tank size of 70 gallons or larger, providing ample space for the fish to move around comfortably. Adequate live rock formations should be included in the aquarium to offer hiding spots for this somewhat shy species.

Demands

Requiring a well-maintained environment, this angelfish species prefers water conditions with a pH level of 8.1-8.4, a specific gravity of 1.020-1.025, and a carbonate hardness (KH) of 8-12. It is crucial to maintain these parameters to ensure the well-being of the Purple Masked Angelfish.

Care and Hardiness

With a semi-aggressive temperament, this species may exhibit assertive behavior as it matures, especially towards fish of similar size and body shape. While generally considered reef-safe, the Purple Masked Angelfish may nip at sessile invertebrates and clam mantles, necessitating caution when housed in a reef environment.

Reef Suitability

The Purple Masked Angelfish can be kept in a reef setup with caution, as it may show aggression towards certain invertebrates. Monitoring the interactions between the angelfish and other reef inhabitants is essential to maintain harmony within the ecosystem.

Aquarium Setup

Setting up the aquarium for the Purple Masked Angelfish should involve providing plenty of live rock structures for hiding places and territorial boundaries. It is advisable to maintain a well-oxygenated environment with appropriate lighting to support the growth of algae, which can serve as a natural food source for this omnivorous species.

Behaviour

Known for its somewhat shy nature, the Purple Masked Angelfish may require time to acclimate to its surroundings before becoming more active. As it grows, the fish may demonstrate increased confidence and territorial behavior, particularly towards tank mates with a similar size and appearance.

Feeding and Diet

Habitat and Distribution

In the wild, the Purple Masked Angelfish is commonly found in the Western Pacific Ocean, particularly in areas with abundant live rock formations and coral reefs. Its natural habitat influences its care requirements in captivity, necessitating the inclusion of suitable hiding spots and a diverse diet to mimic its natural feeding behavior.
