🐟 Red Eye Tetra (Moenkhausia sanctaefilomenae)
A Silvery Body With a Bold, Bright Red Upper Eye • A Black-and-Yellow Band at the Base of the Tail • A Hardy, Active Classic for Larger Community Tanks
📋 The Red Eye Tetra has a silvery-grey body, a bright, iridescent red marking across the upper half of the eye, and a bold black band edged in yellow at the base of the tail.
It comes from a wide range across South America, especially the Paraná and São Francisco river basins, inhabiting clear-water tributaries and streams with dense vegetation. Every Red Eye Tetra we ship is feeding well.
This is a hardy, highly adaptable species and a genuinely active, boisterous swimmer, best kept in a proper school of 6 or more to spread out its energy rather than risk fin-nipping in a smaller group or cramped tank. It reaches up to 7cm, so a 90L tank suits a school well.
