Variola Louti (The Lyretail Grouper)

Overview

• Native to the Indo-Pacific, particularly found in coral reefs, drop-offs, and deep rocky formations.
• Recognized for its vibrant red-to-pink coloration with distinct blue spots scattered across its body.
• A powerful predator known for its ambush-style hunting, preying on smaller fish and crustaceans.
• Can grow significantly in size, requiring a spacious tank and an environment that mimics its natural habitat.
• Best suited for aquariums with ample swimming space, structured rock formations, and stable water parameters.

Feeding

• Carnivorous, primarily consuming fish, shrimp, squid, and other marine invertebrates in the wild.
• Thrives on a diet of frozen seafood such as krill, silversides, and chopped marine fish.
• Readily accepts live food but should be conditioned to eat frozen and prepared diets for long-term health.
• Should be fed multiple times per week with controlled portions to avoid overfeeding.
• A high-protein diet helps maintain its vibrant coloration and overall vitality.

Habitat

• Prefers reef-associated environments with caves, ledges, and areas that offer hiding spots.
• Frequently seen resting within rock crevices, waiting for the opportunity to ambush prey.
• Aquarium setups should include durable rock formations that provide hiding places and visual barriers.
• Requires strong filtration and stable water conditions to support its health and natural behaviors.
• Providing a large, well-oxygenated space encourages movement and exploration.

Fish Care

• Optimal water temperature: 74-80°F (23-27°C) for proper metabolic function.
• Preferred pH range: 8.1-8.4, with a salinity level of 1.020-1.025.
• Requires regular water changes and high-quality filtration to prevent excess nutrient buildup.
• Not reef-safe, as it will consume smaller fish and invertebrates.
• Providing sufficient hiding areas and proper nutrition helps reduce stress and aggression.

Compatibility

• Predatory by nature and best kept with other large, aggressive fish.
• Compatible with large tangs, angelfish, triggers, and other similarly sized carnivores.
• Should not be housed with small fish or delicate invertebrates, as they will likely be consumed.
• Best suited for predator-focused aquariums with ample space and structured territories.
• Providing rock structures and designated territories reduces the likelihood of territorial aggression.

Aquarium Behavior

• A highly intelligent and alert species that actively patrols its territory.
• Frequently observed hiding within rock caves before ambushing prey.
• More confident in a well-established aquarium with sufficient room to swim.
• Providing rock caves and shaded areas helps encourage natural resting and stalking behaviors.
• Over time, it may become accustomed to its caretaker and display responsiveness during feeding times.
