Polleni Grouper Cephalopholis polleni

  The Polleni Grouper (sometimes called the Harlequin Rockcod or Harlequin Hind) is a beautifully colored fish with a green-and-yellow body and yellow-tipped dorsal and anal fins. These groupers have a blue line along their bodies. These fish are difficult to find in the industry; they are a great addition to a large, saltwater-only tank.

Polleni Grouper Feeding Habits

  Due to its size and feeding habits, this fish requires a 250-gallon or larger aquarium. It is a very aggressive fish that may eat its tank mates as well as crustaceans small enough to eat. The Pollenei Grouper prefers to eat meaty foods such as krill, shrimp, and other small fish.
