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 cannot provide about 243 litres for a fully grown fish
  • You keep shrimp you want to protect

A large silver African fish that reaches about 25 cm, rarely imported, and also farmed for food in its native range. Keep a group of at least 6 in 243 litres or more.

Appearance and Identification

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.
