Description

The Chili Rasbora (Boraras brigittae) is one of the most sought-after nano fish in the aquarium hobby. Despite reaching only about ¾ inch in length, these tiny freshwater fish make a huge impact with their brilliant ruby-red coloration, peaceful temperament, and active schooling behavior. They are a perfect choice for planted aquariums, nano tanks, and aquascapes where their vibrant colors truly stand out against lush green plants.

True Boraras brigittae can be surprisingly difficult to find, as they are often confused with or substituted by closely related species such as Boraras maculatus or Boraras merah. At PicKFish Pets, we strive to accurately identify our fish so you know exactly what you’re bringing home.

Chili Rasboras feel most comfortable in groups of at least 8–10 fish, where they display natural schooling behavior and the males develop their deepest red coloration. They thrive in densely planted aquariums with driftwood, leaf litter, floating plants, and gentle water flow. Their peaceful nature makes them excellent tank mates for freshwater shrimp, pygmy Corydoras, Otocinclus, small rasboras, and other tiny community fish.

Although small, they appreciate a varied diet of quality nano pellets, crushed flakes, baby brine shrimp, daphnia, cyclops, and other micro foods. Excellent water quality and stable parameters will reward you with healthy fish displaying their brightest colors.

If you’re looking for a peaceful, colorful nano fish that brings constant movement and life to a planted aquarium, the Chili Rasbora is hard to beat.
