Tank compatibility[edit]

A peaceful community fish that will do well with other similar-sized Tetras and other peaceful community fish. Keep this Tetra in groups of 6 or more. Do not keep with larger predatory fish such as Angelfish.


Will take most foods including pellet and flake as well as live/frozen food such as brine shrimp and daphnia.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

Prefers a spacious tank with ample swimming space as well as hiding places, planted tank compatible. This fish look exceptionally striking if kept in a planted tank with dark substrate.


A mid-swimming active shoaling fish, must be kept in groups or will otherwise become shy and withdrawn.


As the common name suggests, this fish is the same body shape as the more common Neon Tetra, however, the colouration is entirely different. The top half of the body is a pale olive green-brown, the lateral line, rather than being blue in the Neon Tetra, is white in the Black Neon, with the bottom half of the body being black, with a pale belly. The fins are mostly translucent. The top part of the eye is a striking red.
