The Harlequin Rasbora (Trigonostigma heteromorpha or its older name Rasbora hetermorpha) is perhaps the most famous of all rasboras.
A popular aquarium fish suitable for community tanks, it is a small peaceful shoaling species that reaches to a length of 5 cm and can be found in peat swamp forests and forest streams in Malaysia, Singapore, Sumatra and southern Thailand.
It can be easily identified from the black triangular patch on its side. They should be kept in schools of 8-10 and in an aquarium with other peaceful fish. They are quite visually stunning in a group.
In the aquarium, it looks best under subdued lighting and in a densely planted aquarium. It thrives in soft, slightly acidic mature water with pH between 5 to 7 and dH betweem 5 to 12. Breeding the fish requires a species tank containing plants with large leaves. The fish swim upside-down to spawn and lay eggs on the underside of the leaves.

Fast!! Review by stacy
Customer Rating These little guys are so much fun to watch. When I first put them in my tank they shot around at top speed but they have now settled down a bit and often school with my neon tetras. Very pretty fish. Arrived happy and healthy (Posted on 27/11/10)
