Harlequin Rasbora

Harlequin Rasboras are a beautiful, peaceful shoaling species suitable for the community aquarium. They should be kept in groups of at least 6 fish, and preferably more; in the wild, this species moves around in groups of 100+ fish. The aquarium should be well-planted to provide a network of hiding places and much appreciated shady areas. Although this species will acclimatise to a wide range of water conditions, they will be seen at their best in soft, acidic water which mimics their natural environment. Peat filtration is suggested. Similar-looking species are often available in the trade – Trigonostigma espei and T. hengeli have now been joined by the recently described T. truncata from southern Thailand.
