Trigonostigma heteromorpha (Harlequin Rasbora, Расбора гетероморфа)

Harlequin Rasbora, Rasbora heteromorpha, Red Rasbora, Harlequin Fish, Harlequin, расбора клинопятнистая, расбора клиновидная. This cyprinid has been a favorite aquarium fish for about 100 years. It is found on the Malay Peninsula throughout western Malaysia and southern Thailand as well as Singapore. They won't quite reach 2 inches in length and they can be variable in color. They range from a pale pink or bright red to a copper orange along the top and bottom. A school is a must, the companionship of their own species is absolutely essential. You really haven’t seen the Harlequin Rasbora until you’ve seen a school of 10+ individuals in an established tank. These are an excellent schooling fish but the group does need a bit larger aquarium. They are very tolerant fish but do require a little extra care, so are suggested for an aquarist with a bit of experience. They can adapt to a variety of conditions, but optimally they need soft, slightly acidic water and won't do well when kept in hard water. The tank should be carefully covered as these fish are liable to jump if startled or excited. In nature it inhabits forest streams and is primarily found in peat swamps. These are heavily vegetated peaceful waters that are calm or gently flowing. These fish swim in schools and are known as micro-predators, feeding on small insects, worms, crustaceans and zooplankton.
