Harlequin Rasbora (Trigonostigma heteromorpha)

Overview

The Harlequin Rasbora is an absolute classic and a pillar of the Australian fishkeeping hobby. Instantly recognizable by the striking, metallic black "lamb chop" or triangular patch on the back half of their bodies, they feature a gorgeous contrasting copper-orange sheen. They are exceptionally peaceful, hardy, and tight-schooling, making them one of the most reliable choices for any community tank. When settled into a well-planted setup with dark substrate, their colors deepen beautifully, making them a fantastic alternative or companion to traditional tetras.
