Cephalopholis Argus (The Peacock Grouper)

Overview

• Native to the Indo-Pacific, commonly found in coral reefs, rocky outcrops, and lagoons.
• Recognized for its dark brown to blue body adorned with numerous small, iridescent blue spots.
• A predatory species known for its ambush hunting techniques and territorial behavior.
• Can grow quite large and requires a spacious tank with adequate swimming space.
• Best suited for an established marine aquarium with hiding spots and robust tankmates.

Feeding

• Carnivorous, preying on fish and crustaceans in the wild.
• Accepts high-quality marine pellets, frozen shrimp, squid, and live foods in captivity.
• Should be fed a varied diet rich in protein to maintain health and coloration.
• Feedings should be monitored to prevent overfeeding and excessive waste buildup.
• Prefers live or frozen fish but can adapt to prepared foods over time.

Habitat

• Thrives in reef environments with rocky caves and coral overhangs for shelter.
• Prefers stable water conditions with moderate to strong water flow.
• Aquarium setups should include robust rock formations to support hiding and territorial needs.
• Requires a well-maintained marine tank to prevent stress-related issues.
• Providing shaded areas and multiple hiding spots reduces aggression and stress.

Fish Care

• Optimal water temperature: 74-80°F (23-27°C) to support 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 maintain water quality.
• Needs a spacious aquarium due to its predatory nature and territorial behavior.
• Providing a structured environment with caves and crevices supports natural behaviors.

Compatibility

• Highly territorial and best housed with larger, robust fish species.
• Compatible with large tangs, groupers, and aggressive marine fish.
• Not reef-safe, as it will consume smaller fish and invertebrates.
• Should not be housed with timid or smaller tankmates that may become prey.
• Providing ample swimming space and defined territories helps reduce aggressive encounters.

Aquarium Behavior

• A dominant and territorial species that often establishes a preferred hiding area.
• Often seen waiting near rock formations to ambush unsuspecting prey.
• Can be aggressive towards tankmates that encroach on its territory.
• Providing live rock structures and a well-structured tank setup supports natural behaviors.
• Over time, it may recognize its caretaker and display interactive behaviors, particularly during feeding.
