Harlequin Rasbora
Trigonostigma heteromorpha
Adults live in soft, acidic blackwater streams and flooded forest pools, usually close to dense aquatic vegetation. They feed chiefly on small invertebrates, insect fragments, and zooplankton caught in the water column. Its distinctive black triangular flank patch gives this small fish its harlequin-like appearance.
