Description

A peaceful species that won’t compete well with very boisterous or much larger tankmates. Ideally, keep it with other South American species, such as Hemigrammus or Hyphessobrycon tetras, pencil fish, Apistogramma and other small cichlids, Corydoras and Loricariids. In a more general community it can be combined with smaller rasboras, barbs, Anabantoids and West African dwarf cichlids such as Pelvicachromis species.

Always buy a group of at least 6 of these, preferably 10 or more. It’s a schooling species by nature, and will fare much better when in the company of its own kind. The fin-nipping behaviour that is sometimes attributed to this species does not usually manifest itself when it is kept in sufficient numbers, as the fish tend to concentrate on squabbling amongst themselves. Like most tetras it actually looks far more effective when maintained like this anyway.
