The Harlequin Rasbora is an extremely desirable aquarium fish due to its gorgeous metallic color and ease of care. It’s easy to see why so many hobbyists treasure this very peaceful fish. A large school of Harlequin Rasboras will fill the upper area of the aquarium with movement & color to create a lively and vibrant aquarium. The Harlequin Rasbora is easily identified by its black pork chop shaped patch and beautiful copper/orange body. The Harlequin Rasbora does best in an established, well-planted aquarium w/ open areas for swimming. The Harlequin Rasbora should be kept in schools minimum of 8-10 and housed with other small, peaceful fish. The mild nature of the Harlequin Rasbora makes it a great community fish.
Rasbora heteromorpha generally spawns on the undersides of broad-leaved plants. A breeding tank with shallow, warm, acidic, soft water with broad-leaved plants should be set up. To encourage spawning, pair a young (9-12 months old) female Harlequin Rasbora with a two-year old male and offer live food items. After spawning, remove the parents and keep the aquarium dark until the eggs hatch (after about 24 hours). Feed the fry infusoria.
An omnivore, the Harlequin Rasbora does well on a diet of prepared flake food, as well as freeze-dried bloodworms and tubifex.
