Good fit for your tank?

Good fit for

  • A peaceful community tank with similar-sized fish
  • A keeper with room for a proper group of 10 or more

Think carefully if

  • You only want to keep one or two, because this fish needs a group of 6 or more
  • You keep shrimp you want to protect

Appearance and Identification

A large silver African tetra with a dark line on its tail, and adult males have a long, flowing dorsal fin. It ships poorly, but is hardy once settled, and a big group looks stunning.

Check the scientific name when buying, as common names vary between sellers and countries.

Mature females are usually rounder in the belly, and males are usually slimmer and often brighter.

Behaviour and Tankmates

Active and social, and most settled when kept with its own kind.

Keep a group of at least 6, and more if you can. Larger groups are calmer and show better colour and behaviour.

Not territorial, although males may spar and display.

Suits a community of similar-sized, peaceful fish that like the same water. Avoid large predators, which will treat it as food. It is likely to eat shrimp.

Baby foods
  • InfusoriaNeeded for the first days, because most fry are very small.
  • Newly hatched brine shrimpIntroduce as soon as the fry can take it.

An egg scatterer with no parental care. Adults eat eggs and fry, so use a separate tank with fine plants, moss or mesh on the bottom, and remove the adults after spawning. The fry need very small foods at first.
