Very peaceful and will not compete well with very boisterous or much larger tankmates.
In a community it’s best kept with similarly-sized, peaceful characids, smaller callichthyid or loricariid catfishes and sedate surface-dwellers such as hatchetfishes.
It also makes an ideal dither fish for Apistogramma spp. and other dwarf cichlids since it tends to inhabit the middle-to-upper regions of the tank, and does not normally hunt fry.
In a more general community set-up it can be combined with smaller rasboras, barbs, anabantoids, etc.
It’s gregarious and naturally forms schools meaning a minimum of 8-10 specimens is the recommended purchase since the fish will be less shy and display more interesting behaviour.
