Chili Rasbora

To protect our animals and to ensure they get to our customers healthy, we will only ship orders with Nano Fish via UPS Next Day Air.

One of the most popular nano fish in the aquarium hobby, the Chili Rasbora (Boraras brigittae), is well-known and beloved for its peaceful disposition, striking color pattern, and petite size. Also known as the Mosquito Rasbora, the bright ruby red coloration of these fish provides a striking contrast when kept in a planted aquarium. 

Given its small size and schooling behaviors, housing a large number of these fish together creates a mesmerizing display of colors when they swim cohesively around the tank. For them to show off their deep red coloration, we recommend keeping these guys in groups of 10 or more for them to feel safe in a large school.

They occupy the upper and middle sections of the aquarium, occasionally venturing to the bottom areas, particularly when feeling shy or spooked. 

Due to their small size (growing no larger than 0.75”) and peaceful nature, they are readily kept with other peaceful fish of all sizes and invertebrates such as shrimp, snails, and crabs as well. 

The Chili Rasbora can be finicky with water conditions and parameters, particularly when initially introduced to a new aquarium. As such, careful acclimation procedures are recommended. They require clean, high-quality water in order to display optimal coloration. The waters from which they originate are slow-flowing and acidic, with high tannin levels and leaf litter. Dark substrate in their tank will really help make their colors pop! 

Chili Rasboras are not particularly picky eaters, and will thrive and remain very colorful on prepared foods, whether they be dried or alive. Many fish keepers have great success with flake, pellet, and other dry goods. However, they won’t deny some good live foods such as baby brine shrimp, daphnia, or blood/tubifex worms. Watching a school of these fish chase down their prey is a sight to behold!
