<i>Rasbora</i> Genus of fishes

Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.

<span class="mw-page-title-main">Harlequin rasbora</span> Species of fish

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, would grace the cover of the first edition of William T. Innes's classic Exotic Aquarium Fishes and would remain so through all 19 editions.

<i>Sundadanio axelrodi</i> Species of fish

Sundadanio axelrodi is a danionin in the family Cyprinidae, with origin from Borneo, Bangka, and Sumatra. Originally described as a rasbora, Rasbora axelrodi, this tiny species was later deemed to be more closely related to the danios but not enough to be moved into the genus Danio. Sundadanio axelrodi reaches a maximum size of 1.7 cm. Sundadanio was considered monotypic until the genus was reassessed by Conway, Kottelat and Tan in 2011.

<span class="mw-page-title-main">Eyespot rasbora</span> Species of fish

The eyespot rasbora is a small fish belonging to the Family Cyprinidae, subfamily Danioninae, which is known by the common names of ocellated rasbora, hi-spot rasbora, and eye-spot rasbora, an allusion to the marking situated upon the dorsal fin. This small fish is a popular aquarium fish, having been one of the species featured in the landmark textbook Exotic Aquarium Fishes by Dr William T. Innes. Its appearance in this work only occurs in later editions of the book, however, therefore the species is not subject to the same degree of aquarium domestication as the more familiar harlequin rasbora.

<span class="mw-page-title-main">Danionin</span> Subfamily of fishes

The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera Danio, Devario, and Rasbora. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Danio species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Devario species tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.
