The Leopard Grouper, also known as the Cabrilla Grouper, is a powerful and eye-catching saltwater fish known for its beautiful leopard-like spots and strong predatory presence. Found in the eastern Pacific Ocean, particularly around the Sea of Cortez, this grouper is admired for its unique markings and commanding behavior in large marine aquariums.

Due to its size and diet, the Leopard Grouper is best suited for experienced aquarists who can provide a large tank, strong filtration, and appropriate tank mates.

Key Features

• Hardy, long-lived, and adaptable in well-maintained aquariums.

• Can grow quite large, making it a true showpiece fish.

• Best suited for advanced aquarists with large saltwater systems.

Water Conditions & Tank Setup

Leopard Groupers require large, stable saltwater environments to thrive:

• Tank Size: Minimum 300 gallons (larger strongly recommended).

• Temperature: 74°F – 80°F (23°C – 27°C).

• pH Level: 8.1 – 8.4.

• Salinity: 1.020 – 1.025 specific gravity.

• Filtration: Strong filtration and protein skimmer required due to high bioload.

• Aquascaping: Provide solid rock structures and caves for hiding, along with open swimming areas.

Behavior & Tank Mates

Leopard Groupers are predatory and territorial. They require careful selection of tank mates:

• Suitable tank mates include other large, robust marine fish such as:

  • Large Angelfish

  • Tangs

  • Triggerfish (non-aggressive species)

  • Large Wrasses

• Avoid small fish, shrimp, and crabs—they will be eaten.

• Not recommended to house with other groupers due to territorial aggression.

Feeding Habits

The Leopard Grouper is a carnivore with a protein-rich diet:

• Feeds on meaty foods such as shrimp, squid, fish fillets, and clams.

• May accept large marine pellets over time.

• Do not rely on feeder fish as they can introduce disease.

• Adults can be fed 2–3 times per week, while juveniles may need more frequent feeding.

Care & Maintenance

• Requires excellent water quality and strong tank circulation.

• Weekly water changes (15–20%) recommended.

• Produces heavy waste—strong filtration is a must.

• Lifespan: 10–15 years in captivity with proper care.

• Best kept by experienced marine aquarists due to size and predatory nature.
