Centropyge Vroliki (The Half Black Angelfish)

Overview

• Native to the Indo-Pacific, commonly found in coral reefs, lagoons, and rocky reef formations.
• Identified by its striking two-tone coloration, with a dark black posterior half and a lighter front half.
• A hardy and adaptable species that thrives in well-maintained aquariums.
• Can be territorial, particularly towards other dwarf angelfish, requiring careful selection of tankmates.
• Best suited for a mature marine aquarium with ample rockwork for hiding and grazing.

Feeding

• Omnivorous, feeding on algae, sponges, and small invertebrates in the wild.
• Accepts high-quality marine pellets, frozen foods, and algae-based diets in captivity.
• Providing sponge-based foods is beneficial for long-term health and coloration.
• Multiple small feedings per day ensure sustained energy and proper nutrition.
• A varied diet supports immune health and helps maintain its vibrant appearance.

Habitat

• Prefers reef environments with rocky crevices and coral formations for shelter.
• Thrives in stable water conditions with moderate to strong water flow.
• Aquarium setups should include live rock structures to encourage grazing and natural behaviors.
• Requires a well-maintained marine tank to minimize stress and promote long-term health.
• Providing shaded areas and multiple hiding spots reduces aggression and territorial disputes.

Fish Care

• Optimal water temperature: 74-80°F (23-27°C) for maintaining overall health.
• Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires efficient filtration and regular water changes to keep water conditions stable.
• Introducing it to an established aquarium with live rock helps ease the acclimation process.
• Providing a structured environment with caves and crevices supports natural behaviors.

Compatibility

• Semi-aggressive, particularly toward other dwarf angelfish and similarly sized fish.
• Compatible with tangs, wrasses, and other semi-aggressive reef fish.
• Not entirely reef-safe, as it may nip at soft corals and sessile invertebrates.
• Should not be housed with overly aggressive species that may cause stress or outcompete it for food.
• Providing ample swimming space and defined territories helps reduce territorial behavior.

Aquarium Behavior

• An inquisitive and active species that enjoys exploring its environment.
• Often seen darting around rock formations and grazing on algae.
• Can become territorial in smaller aquariums or when housed with similar species.
• Providing live rock structures and a well-structured tank setup supports natural behaviors.
• Over time, it may become more comfortable with its caretaker and exhibit interactive behaviors, particularly during feeding.
