Grouper

Groupers are bold, beefy fish that need room to stretch out—most will hit 12 inches or more, so plan for a big tank with lots of caves and hiding spots. They’re not the most social types, so it’s best to keep just one per setup to avoid turf wars, unless it’s a tank full of predators.  These predators have a serious appetite, usually going after smaller fish or crustaceans. Definitely not reef safe, but undeniably cool if you’ve got the space.

Grouper aren’t the type to blend into the background. These tank titans are big, bold, and full of personality. Known for their stocky build, strong jaws, and commanding presence, groupers bring a wild ocean vibe straight into your home aquarium. If you’re ready for a fish with attitude, you’ve come to the right place.

Spotlight on Our Groupers

Miniatus Grouper

With its fiery red body and bright blue spots, the Miniatus Grouper (Cephalopholis miniata) is equal parts beauty and beast. This predator is a showstopper, but don’t let its good looks fool you—when it’s hungry, it means business. It can grow up to 14 inches, so make sure it has room to roam.

Panther Grouper

If you want a fish that makes a statement, the Panther Grouper (Cromileptes altivelis) is the one. With its sleek white body and bold black spots, it stands out in any setup. But don’t be fooled by its playful pattern—this species can grow over two feet long and needs plenty of swimming space.

Strawberry Grouper

The Strawberry Grouper (Cephalopholis spiloparaea) adds a burst of color to any tank with its reddish-pink body speckled with tiny blue spots. It stays smaller than some of its grouper cousins, usually maxing out around 10 inches, but still packs plenty of personality. A great pick for those wanting a bold, manageable predator with flair.

Caring for Groupers

These fish are built to last, but they have some key needs to thrive.

  • Diet: Carnivores with a serious appetite—think fish, shrimp, and other meaty seafood.
  • Tank Setup: Large tanks with rock structures for hiding. These guys like their personal space. 
  • Behavior: Generally peaceful toward similar-sized fish, but anything smaller might end up as a snack.
