Chili Rasbora (Boraras brigittae) – Nano Freshwater Aquarium Fish

The Chili Rasbora (Boraras brigittae) is a stunning nano freshwater fish prized for its intense red coloration, peaceful temperament, and tiny size. Perfect for planted aquariums and nano tanks, Chili Rasboras add vibrant movement and color without overwhelming smaller setups. These schooling fish thrive in soft, acidic water and are ideal for aquarists looking to create a natural, Southeast Asian biotope aquarium.

🌍 Origin

Chili Rasboras are native to Borneo, Indonesia, where they inhabit slow-moving blackwater streams, peat swamps, and densely vegetated areas. In the wild, they are found in tannin-rich waters shaded by forest canopy, which contributes to their preference for subdued lighting and planted environments.
