Harlequin Basslet (Serranus tigrinus)

Max Size: 11.5 inches
Diet: Carnivore
Temperament: Semi-Aggressive
Reef Compatible: With Caution. May eat smaller fish and crustaceans
Minimum Tank Size: 75 gallons

The Harlequin Bass is a unique and visually striking fish with a yellow and black mottled color on the ventral side and black and white mottling on the dorsal half. It is a hardy species and suitable for beginners. For a good environment, a 75-gallon or larger aquarium with plenty of hiding places is recommended.

As the Harlequin Bass matures, it may prey on smaller fish or small crustacean tank mates. While they can be dominant towards smaller tank mates, they are not usually aggressive towards dissimilar species. However, they do not usually get along with other Dwarf Sea Basses or bottom-dwelling fishes that occupy the same territory. It is recommended to keep only one Harlequin Bass per tank unless a bonded pair can be obtained.

To maintain their health, the Harlequin Bass requires a diet consisting of a variety of chopped live meaty items and frozen foods.
