Purple Harlequin Rasbora

The Purple Harlequin Rasbora is a vibrant and peaceful freshwater fish known for its striking purple and rose-colored tones. Its body shimmers with shades of metallic violet and pink, accented by the signature black triangular patch that gives the Harlequin Rasbora its name. These small, active fish add a beautiful splash of color and movement to any community aquarium.

Native to the slow-moving streams and peat swamps of Southeast Asia, the Purple Harlequin Rasbora thrives in soft, slightly acidic water with plenty of plants and open swimming space. They feel most comfortable in schools of six or more, where their natural shoaling behavior can be fully appreciated. Watching a group swim together in harmony is both calming and captivating.

This rasbora species is peaceful and pairs well with other gentle community fish such as tetras, corydoras, guppies, and dwarf gouramis. Avoid housing them with large or aggressive tank mates that may intimidate or outcompete them for food.

Feeding is simple, as the Purple Harlequin Rasbora is an omnivore. They readily accept flakes, micro pellets, frozen foods, and small live foods such as daphnia or brine shrimp. A varied diet helps enhance their vibrant purple and pink coloration.
