The Panther Gouper is one of the most common Groupers in the market. Its a small fish at birth, a beautiful white with large black spots. Eventually, they grow into colossal fish swallowing anything small enough to fit in its mouth. Their large spots shrink and become numerous with age.

This grouper is a hardy fish and is an excelent beginner fish. Must be kept in a 150 gallons+ tank with plenty of hiding places as it will grow big in a small period of time if fed properly. Beware as this fish will swallow anything small enough to fit into its mouth. It will ignore any other medium sized fish or larger than itself, and can be kept in a group in a large tank.

20" as an adult

Minimum Tank Suggestion

Ideal water parameters for Panther Grouper

Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
