Harlequin Rasbora

Trigonostigma heteromorpha — 三角燈

The Harlequin Rasbora is one of the most recognizable and popular schooling fish, distinguished by its distinctive dark triangular patch on a coppery-orange body. Native to the peat swamps and streams of Southeast Asia, it prefers soft, slightly acidic water. An incredibly peaceful and hardy species that looks spectacular in large schools.
