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

Feeding Habits

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

• 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

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

• Produces heavy waste—strong filtration is a must.

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