Chili Rasbora (Boraras brigittae)
The Chili Rasbora is one of the most vibrant and sought-after nano fish in the freshwater aquarium hobby. Despite reaching just under an inch in length, this tiny species dazzles with its brilliant crimson-red body, bold black lateral stripe, and fiery orange fins. When kept in a lush planted aquarium, a school of Chili Rasboras creates a stunning display of color and movement, making them a favorite among aquascaping enthusiasts.
Native to the blackwater peat swamps and slow-moving forest streams of Borneo, Chili Rasboras thrive in calm, heavily planted environments with dark substrate, driftwood, leaf litter, and subdued lighting. These peaceful fish are highly social and should be kept in schools of at least 10 or more. Larger groups encourage natural schooling behavior, reduce stress, and enhance their vibrant coloration.
Chili Rasboras prefer mature aquariums with stable water conditions and gentle water flow. Due to their tiny mouths, they require appropriately sized foods such as crushed flakes, nano pellets, baby brine shrimp, microworms, daphnia, and other small live or frozen foods. A varied diet helps maintain their intense red coloration and overall health.
Their gentle nature makes them ideal tank mates for other nano fish, pygmy Corydoras, otocinclus, peaceful shrimp, and small snails. They are especially well suited for planted nano aquariums where their vivid colors contrast beautifully against lush green plants and dark aquascaping materials.
