It’s a very peaceful species that won’t compete well with very boisterous or much larger tankmates. Ideally keep it with other South American species, such as other small tetras, pencil fish, hatchet fish, dwarf cichlids such as Apistogramma, Corydoras and small Loricariids.
In a more general community it can be combined with smaller rasboras, barbs, livebearers, loaches, 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 shoaling species by nature, and will fare much better when in the company of its own kind. Like most tetras it actually looks far more effective when maintained like this anyway.
This is the Albino variant
