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 Hyphessobrycon or Hemigrammus species, pencil fish, Apistogramma and other dwarf cichlids, Corydoras and small Loricariids. In a more general community, it can be combined with smaller rasboras, barbs, Anabantoids and West African dwarf cichlids such asPelvicachromis species. Due to its shape, it’s also safe to be kept with larger cichlids such as angel fish or discus.
Always buy a group of at least 6 of these, preferably 10 or more. It’s a shoaling species by nature.
