Harlequin Rasbora, Trigonostigma heteromorpha

The Harlequin Rasbora is fairly popular, because it is a hardy community fish that can tolerate variations in pH levels.  It originates from the Thailand and Malaysia area.  It has a pinkish body with a black triangle filling most of its back half.  It likes lots of plants and dim lighting, which actually helps enhance its color.  Harlequin Rasbora should be kept in schools of 8 - 10.

Females are slightly larger than the males. Eggs are spawned on the underside of broad leaves and surfaces.  After spawning, remove the parents and keep the aquarium dark until the eggs hatch a day later. Feed the fry infusoria or brine shrimp.
