Harlequin Rasbora
Rasbora heteromorpha
The Harlequin Rasbora is one of the most popular aquarium fish. These fish have a black triangle-shaped patch starting near the dorsal fin. The male's patch is slightly rounded at the bottom with an extended tip while the female's is straight. Females are larger than the males.
Harlequins requires an established planted aquarium. They should be kept in schools of 8-10 and in an aquarium with other small, peaceful fish.
Rasbora heteromorpha generally spawn on the undersides of broad-leaved plants. A breeding tank with shallow, warm, acidic, soft water with broad-leaved plants should be set up. Pair a young female (9-12 months old) with a two-year old male and feed them live foods. After spawning, remove the parents and keep the aquarium dark until the eggs hatch (after about 24 hours). Feed the fry infusoria.
An omnivore, Harlequin Rasboras do well on a diet of prepared flake food, as well as freeze-dried bloodworms and tubifex.
