Betta Rubra

Betta rubra is a striking betta native to the north-western reaches of Sumatra, with a documented range from Meulaboh to Sibolga. This species has been formally re-described based on freshly collected preserved and live specimens, giving aquarists and researchers a clearer understanding of its distinctive appearance and defining traits.

• Iridescent light blue patch at the pectoral fin origin creates a subtle, eye-catching glow that stands out against its darker body planning.
• Ventrolateral flank pattern of alternating black bars and red blocks delivers a bold, geometric contrast across the midsection, making it highly recognizable in a display tank.
• Dark triangular patch below the eye adds a sharp facial marker that helps distinguish this species in any mixed bassline or species showcase.
• Absence of red twin bars on the opercle when preserved provides a reliable, diagnostic cue for identification, helping hobbyists separate Betta rubra from similar relatives.

This combination of markings—paired with the regionally specific distribution—gives Betta rubra a unique visual signature that appeals to serious collectors, taxonomy enthusiasts, and display aquariums alike. The emphasis on fresh-specimen observations in its re-description ensures buyers understand the integrity of its identifying features and the careful attention given to documenting its morphology.

Why this Betta rubra stands out for your collection:

• Scientific provenance: A recent re-description grounded in fresh material enhances confidence in accurate identification and authenticity.
