Purple Harlequin Rasbora (Trigonostigma heteromorpha – Selective Strain) – A Regal Twist on a Classic Favorite
The Purple Harlequin Rasbora is a selectively bred variant of the well-known Harlequin Rasbora, featuring a deeper, more violet hue than its traditional orange-pink counterpart. Native to Southeast Asia, this striking strain maintains the iconic black triangular patch on its body but adds a unique royal sheen that stands out beautifully in planted aquariums.
Its peaceful temperament and tight schooling behavior make it an ideal choice for community tanks. The rich purple coloration becomes more vivid in well-maintained tanks with subdued lighting and a dark substrate.
