The colours of the adult fish shine through, with movement and bring a rainbow of blue and green to the fish.
It is not until they begin to become sexually mature that these fish really develop their colours, and females may remain drab. They are best kept in a mixed sex shoal, as males will not display well unless they have females to display to.
All species of Congo Tetras are generally quite easy to maintain, and are also a reasonably easy tetra to spawn, particularly in a summer tub. They are Hardy but ideally prefer slightly acid to neutral water. Tanks should be planted at the back with tall plants leaving lots of open space for these active swimmers. Generally peaceful but care should be taken with angels as they could nip the free flowing fins of the congos
