Diet
A micropredator feeding on tiny invertebrates and other zooplankton in nature.In the aquarium it will accept dried foods of a suitable size but should also be offered daily meals of small live and frozen fare such as Artemianauplii, Moina, grindal worm, etc.Relatively 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 and smaller callichthyid or loricariid catfishes but sedate surface-dwellers such as hatchetfishes are best omitted, especially in smaller aquaria.It also makes an ideal dither fish forApistogramma spp. and other dwarf cichlids since it tends to inhabit the middle-to-upper regions of thetank, and does not often predate fry.In a more generalcommunity set-up it can be combined with smaller rasboras, barbs, anabantoids, etc.Buy as many as possible, ideally 10 or more, as when kept in larger groups any aggression is spread between individuals plus the fish are bolder and exhibit more natural behaviour.
