Aquarist Atlas · piranhas, pacus & the big characins

Every characin on one map

34,338 georeferenced records across 868 species. These are the characins the Tetras section leaves out, and they belong to two continents. The piranhas and pacus (Serrasalmus, Pygocentrus, Colossoma), the silver dollars, the headstanders, the wolf fish (Hoplias), the payara and pike characins fill South America from the Orinoco to the Paraná; the African characinsDistichodus, the citharinids and the pike-characin Hepsetus — light up the Congo, Nile and West African rivers. Colour the cloud by group, 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 34,338 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 (Serrasalmidae has been split hard in recent years, so many silver dollars are still indexed under a former genus such as Myleus, and pacus under Colossoma). 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 landing) rather than the precise catch site, some are historical or low-precision, and the occasional point may be a misidentification, an aquaculture record, or a feral occurrence well outside the native range — the pacus in particular are farmed and released worldwide, so we keep only points that fall inside the native-range boxes of South America and Africa. Many small, recently-described characins have no public records yet — an empty map is honest, not an error. No coordinates are invented.
