The Panther grouper, or Cromileptes altivelis, is a large and appealing species that can provide plenty of entertainment in your saltwater tank, with a unique look featuring black dots over a white body. If you can handle a more predatory fish and have the space to keep it, the Panther grouper may make a good addition to your aquarium with the proper care.

This guide to the Panther grouper will help you decide whether this fish is ideal for your tank.

Is the Panther grouper reef safe?

The Panther grouper is technically reef-safe in that it won’t nip at your corals, but this species will go after any shrimp and other inverts in your reef tank as predators with a diverse appetite. So, it really comes down to whether you want to keep a reef tank with crustaceans and other invertebrates as features or prey.

Panther grouper food and diet

The Panther grouper is large and loves to eat many meaty foods. You can feed this fish just about any type of meat imaginable to keep it satisfied, including shrimp, squid, calms, krill, and other smaller fish. You may also be able to supplement meaty foods with dried fish foods specifically for feeding carnivorous species.

As the fish grows, consider sticking with more live foods, which allows the fish to exercise its hunting prowess and can provide some entertainment.
