Polleni Grouper - Cephalopholis polleni

The Polleni Grouper is a visually striking and sizable fish, featuring a predominantly yellow body adorned with bold purple stripes. As they age, their coloration deepens. These groupers can grow up to 17 inches and require a minimum tank size of 220 gallons. Known for their aggressive nature, they should not be housed with smaller, passive fish, and they may also target invertebrates. Caution is advised when adding a Polleni Grouper to a reef aquarium.

Ideal for larger, fish-only setups, the Polleni Grouper brings vibrant color to your tank. They thrive alongside other large, semi-aggressive to aggressive species. Given their size, ample swimming space is essential. As carnivores, their diet should include meaty foods. Juveniles benefit from mysis and brine shrimp, while adults require larger seafood portions.
