A dependable fish for intermediate and advanced hobbyists, but needs a large tank, as it is a large tetra that must be kept in schools. This species cannot tolerate poor water conditions, so frequent water changes are necessary.

Open swimming space is necessary to show off this fish, with suitable hiding places along the back and sides. A planted tank is perfect. An excellent community fish with non-aggressive species of similar size, this fish can be timid.

Omnivorous, should have some vegetable matter, but most of the diet should be meaty. Like most tetras, this fish particularly relishes live foods. Although large, they can lose out at mealtime to more boisterous feeders. They may nibble on soft plants.

Congo River

 

Congos are considered moderately difficult tetra to spawn. Condition the breeders with live foods, then provide warm, soft, acid water with plenty of plants or artificial spawning grass.

A robust tetra with beautiful finnage-extra long in the male, especially the dorsal fin and the extensions of the middle rays in the caudal. The colours are iridescent, primarily blue and bronze, with green and violet shimmering as the lighting changes.

This is the most popular of the African tetras. They are relatively expensive, so people often buy only a couple, but they are truly at ease only in large schools, and a dozen or two of these fish in a long tank makes a magnificent display. It is difficult to describe their beauty, or to capture it faithfully in a photo.
