Sexing[edit | edit source]

Sexually mature males are smaller and more brightly coloured than the females.

Tank compatibility[edit | edit source]

An easy-going fish that should be compatible with similar-sized peaceful community fish. Avoid anything with long fancy fins though as they may be fin-nipped. Should be kept in groups of at least 6.

Diet[edit | edit source]

Will accept most foods including pellet and flake as well as live/frozen food such as daphnia and brine shrimp. They have a small mouth so need fine granule foods.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

Appreciates a spacious tank with dense planting and plenty of hiding places. Prefers subdued lighting. Does best in acidic water.

Behaviour[edit | edit source]

A peaceful shoaling fish.

Identification[edit | edit source]

An attractive little silver-coloured fish with a bold black lateral line with a band of iridescence above this.
