Harlequin (Heteromorpha) Rasboras!
The Het. Harlequin Rasbora is one of the more popular Rasboras and very commonly available in the hobby. Many people often mistake it for a tetra, but it is a member of the cyprinid family, which all have two barbs on the sides of the upper lip. While they are small, if you look close, you will see the thin barbs on its mouth as it turns in the water. It grows to approximately two inches and is very subtly but often beautifully colored. The common name alludes to the black triangular patch on the body, reminiscent of the patterns found on the costume of a harlequin. The genus name "Rasbora" comes from an Indian word meaning "fish"!
They have an iridescent, pearly sheen to their body when kept in subdued light, but it sometimes may fade out under the bright lights of a normal aquarium. Found in Asia, Thailand, Sumatra and Indonesia, they inhabit forest streams forming small shoals, and feeding on insects, crustaceans, and aquatic worms. Fun Fact: Singapore issued a ten cent postage stamp bearing its image!
The Harlequin Rasbora is quite adaptable and easy to care for as long as the water is kept clean and basic care requirements are met. It is also a shoaling fish, and would be best kept in numbers of about 6 or more. They are a peaceful species of fish and can be kept in a community - just be sure to include plenty of aquatic plants and hiding spaces where they can retreat if they feel the need and to best duplicate their natural habitat.
Rasboras are great in a group and can be tankmates with many Tetras, Danios, Barbs, and even the Panda Cory Catfish that is also on sale now at only $5.99! Right now until July 15, too, you can get your very own Harlequin Rasboras for just $1.99 each at Uncle Bill's Pet Centers!
