Scientific name: Rasbora heteromorpha
The quiet Harlequin Rasbora grows to 1.5 inches and is best kept in small groups. Dark aquascaping and subdued light suit it best. As long as the water temperature is between 74º and 82º Fahrenheit, the pH between 6.0 and 7.0, and the water moderately soft, this fish will do well. Flake and freeze-dried foods will provide a sufficient diet.
The Harlequin Rasbora is a muddled orange and pink with a prominent blue-black wedge that starts midbody and tapers back to the tail. The coloring is usually more pronounced in the males. A small, timid fish, it should not be kept with more active or aggressive species.
