Harlequin rasbora

Harlequin rasbora

The harlequin rasbora is a small fish in the family Cyprinidae. The species became an instant favorite among aquarists after its introduction in the early 1900s and is the best known and most widely kept species among the rasboras. In 1935, an image of a trio of harlequin rasboras, stamped in 14k gold, graced the cover of the first edition of William T. Innes's classic Exotic Aquarium Fishes, and remained through all 19 editions.

Life Span 5-15 years

What to Know Before Buying a Harlequin rasbora

Finding a responsible Harlequin rasbora breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells fishs commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.

Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the Harlequin rasbora. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.

Use the search tool below to check whether any USDA-licensed facilities breeding Harlequin rasboras appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
