Chili Rasbora
Boraras brigittae
About
The chili or mosquito rasbora is a tiny Boraras from Indonesian peat swamps, famous for intense red colour in soft, acidic water. It needs a mature planted nano or small tank, gentle filtration, and a large school (ten or more) for confidence and colour. Not a fish for hard alkaline tap water without adjustment—RO blending or peat use is common. Peaceful with shrimp and other microfish; may be outcompeted by boisterous species. Egg scatterer; eggs tiny; infusoria-grade first foods for fry.
