The Harlequin Rasbora is an extremely desirable aquarium addition thanks to its gorgeous metallic coloration and ease of care. It's not difficult to see why so many hobbyists treasure it. A large school of Harlequin Rasboras fill the upper areas of the aquarium with movement and color so lively and vibrant that even non-hobbyists marvel at the display.
The Harlequin Rasbora is easily identified by its characteristic black "pork chop" shaped patch. Males will have a beautiful lustrous copper/orange body while females will be exhibit a more golden coloration . The distinguishing triangular patch begins near the dorsal fin and comes to a point near the base of the caudal fin. The patch on the female Harlequin Rasbora is slightly rounded at the bottom with an extended tip. In contrast, the patch on the male Harlequin Rasbora is straight. The female Harlequin Rasbora is also larger than the male. Juveniles will darken as they mature.
The Harlequin Rasbora does best in an established planted aquarium with open areas for swimming. The Harlequin Rasbora should be kept in schools of 8-10 individuals and housed with other small, peaceful fish. The mild nature of the Harlequin Rasbora makes it a great community fish.
