A flashy African species best kept in schools of three or more. Aaron Norman

Overview

Here is a classy species that literally sparkles. It is a popular aquarium fish that is also quite hardy. To truly appreciate the Congo Tetra’s appearance, place the aquarium in an area where there is some natural light. Full-spectrum aquarium lights will also help.

Family: Alestiidae

Other common name(s):

Native range:

Habitat: Although the Congo Tetra can be kept in smaller aquariums, these are active swimmers that are always on the go and will do best in long rather than tall tanks to provide them with lots of room. Plant sparsely on the sides and back, and provide a dark substrate and background, which will go a long way toward showcasing their colors.

Maximum length: 8 cm (3 in)

Minimum aquarium size: 114 L (30 gal)

Water: Freshwater 23 °C (73 °F) - 26 °C (79 °F)

General swimming level: Mid-water to top.

Feeding

Omnivore. In the wild eats insects, worms and vegetative matter.

Aquarium Compatibility

The Congo Tetra is an active, schooling species that should be kept in groups of at least three (the more, the better). They are extremely peaceful and can be mixed with most mild-mannered community fishes. Avoid fin nippers like Tiger Barbs or Redeye Tetras, as these may bite the flowing fins of the males.

Breeding/Propagation

Egg scatterer. Males develop flowing dorsal fins and a extended trident-like tail.

Notes

They are somewhat skittish, so place the tank in a low-traffic area and provide a cover of floating plants to diffuse the lighting. Regular water changes are a must.
