Species of fish

The harlequin rasbora (Trigonostigma heteromorpha) is a small fish in the family Cyprinidae.[2] 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.[3] In 1935, an image of a trio of harlequin rasboras, stamped in 14k gold, would grace the cover of the first edition of William T. Inness classic Exotic Aquarium Fishes and would remain so through all 19 editions.[3]

The species was originally classified into the genus Rasbora, and given the specific name heteromorpha (Greek, "differently shaped") to alludes to the fact that its body shape differed from other members of that genus. The common name alludes to the black triangular patch on the body, reminiscent of the patterns found on the costume of a harlequin.
