About
Boraras brigittae — often sold as the Chili Rasbora — is one of the most iconic nano fish in the hobby. Native to peat swamps and blackwater streams of southern Borneo, it thrives in heavily tannin-stained, soft, acidic water. Males are more intensely coloured and display to each other constantly, making a large school mesmerising to watch.

Feeding: Accepts micro pellets, baby brine shrimp, and crushed flake; feed twice daily. Behaviour: Peaceful micro schooler; keep 10+ for best colouration and confidence.
