Aquarist Atlas · the danios & rasboras

Every danio & rasbora on one map

3,924 georeferenced records across 230 species, drawn across the fresh waters of tropical Asia — the monsoon hill streams of the Western Ghats and Sri Lanka, the rivers and rice paddies of the Gangetic plain and Myanmar, the great floodplains of the Mekong and Chao Phraya, and the tannin-black peat swamps of Sundaland. Colour the cloud by group — the true and giant danios, the micro and transparent danios, the flying barbs, and the rasboras and dwarf rasboras — or switch to compare mode and read two species’ ranges against each other.

About this map. Scroll or pinch to zoom, drag to pan, and click a dot to identify the species. The 3,924 dots are real occurrence records pulled from GBIF, the Global Biodiversity Information Facility — an aggregator of museum specimens, scientific surveys and verified citizen-science sightings — queried for both each fish’s current name and its older genus combination (danio and rasbora genera have been reshuffled repeatedly). Treat them as a guide to where a species lives, not exact spots: many records are georeferenced to a locality centroid (a nearby village or river mouth) rather than the precise catch site, some are historical or low-precision, and the occasional point may be a misidentification or a record from outside the native range. Many tiny and recently-described danios and rasboras have no public records yet — an empty map is honest, not an error. No coordinates are invented.
