Cephalopholis argus | L

Cephalopholis argus, commonly known as the Peacock Grouper, is a visually captivating marine fish prized for its distinctive blue-ringed spots and robust body. This large grouper species is best suited for advanced marine aquarium enthusiasts due to its size and specific care requirements.

Temperament and Compatibility: Cephalopholis argus is a predatory and territorial fish. It can be aggressive towards smaller tank mates and conspecifics, so it is recommended to keep it with similarly sized or larger species. Avoid housing with small, peaceful fish to prevent predation.

Diet: This species is carnivorous and thrives on a diet of meaty foods such as live or frozen crustaceans, fish, and specialised marine pellets. Feeding should be regular and varied to maintain optimal health.

Tank Requirements: Due to its potential size and active nature, a minimum tank size of 300 litres is advised to provide ample swimming space and territory. The aquarium should include plenty of live rock for hiding and ambush hunting.

Water Parameters and Environment: Maintain stable marine conditions with a temperature range of 24-27°C, salinity between 1.020-1.025 SG, and moderate water flow. Lighting requirements are standard for marine fish and should support the overall reef environment if applicable.

Reef Safety: Cephalopholis argus is not reef safe as it may prey on smaller invertebrates and fish within a reef setup.

Overall, the Peacock Grouper is a stunning addition to a large, well-established marine aquarium, offering a dramatic focal point for experienced hobbyists.
