Flame tetra
Hyphessobrycon flammeus
A tetra of intense chromatic warmth: the rear half of the body grades from orange-red to fiery red, like a living flame. Also known as 'Von Rio' for its origin in coastal rivers around Rio de Janeiro, Brazil. Wild populations are now severely threatened, making captive-bred specimens vital for conservation. Robust, long-lived and peaceful, it is one of the easiest tetras to keep and breed. In schools of 6–8+ on dark substrate with dim lighting and tannins, the coloration reaches spectacular depth.
