With gorgeous color and unique pattern, the Harlequin Bass makes a beautiful addition into any aquarium. The Harlequin Bass has a long pointed snout with black stripes and bars that form vertical rectangles on its body. Along with this, it features yellow chin and belly that makes the Harlequin Bass more attractive. Since it is easy to care and hardy in nature, the Harlequin Bass makes a very good choice for a beginner aquarist. As it matures, it grows up to 11 inches and is best to keep in a tank not less than 30 gallon. The Harlequin Bass loves to spend its time perching in, on, and around the rocks and caves, thereby plenty of live rocks and caves are necessary to add in the tank. It may prey on smaller crustaceans like shrimp and crabs, which makes it safe in reef tank but with caution. The Harlequin Bass can be fed with variety of foods that include frozen or fresh shrimp, clam, scallop, brine shrimp, mysis shrimp, krill and similar items. It thrives well in a temperature range of 74-82 degrees Fahrenheit and a pH of 8.0-8.4. Being semi-aggressive it can get along with larger community fish, but may be found intimidating smaller fish or crustacean tank mates. The Harlequin Bass requires plenty of hiding places to make it feel comfortable and it needs a thick sand bed in the aquarium, as it prefers to dig in the bottom substrate.
