Dwarf golden barb is an ideal species for quieter temperate aquariums. As a shoaling species, they must be maintained in groups of at least 6 specimens, and more where space permits. In the wild, Dwarf golden barbs are often found in clean, slow moving waters, so the aquarium should be well-filtered but with a gentle current. Plenty of plant cover must be provided in order for these shy but peaceful fish to feel secure. Not suitable for housing with large or boisterous fish, and because this species prefers temperatures at the lower end of the tropical range, ensure that other tankmates have the same needs. Dwarf golden barbs have a reputation for being a little delicate, but with sensible acclimatisation procedures and good water conditions/maintenance, problems should not be encountered.
 
Although know as Pethia gelius for decades, a few species may be labelled as Dwarf golden barbs, with the most common possibly being P. aureus but P. canius also appears frequently with true P. gelius being the least commonly imported. Telling them apart can be tricky, fortunately their care is similar. 
Feeding
Flake, micropellets, small frozen foods such as mosquito larvae, baby brineshrimp, daphnia, cyclops etc.
Breeding
This species will spawn in a heavily planted shallow aquarium. Eggs will be scattered over fine leaved plants, often when the first rays of morning sunshine hit the aquarium glass. The parent fish should be removed as soon as spawning has ceased in order to prevent them from predating on the eggs. The fry can be very difficult to raise due to their diminutive size and delicate nature.
