Yellow tetra
Hyphessobrycon bifasciatus
A tetra with golden-yellow hues glowing on fins and silver body, with two thin dark lateral bands. Native to coastal river systems of southeastern Brazil, it is a robust, adaptable tetra that tolerates a wide parameter range. Peculiarity: wild specimens may show golden coloration caused by a trematode parasite of the natural biotope — a harmless, purely aesthetic phenomenon absent in captive-bred specimens. Prefers slightly cooler temperatures (20–25 °C) than the tropical average. Breeding among the easiest for characids.
