Golden Dwarf Barb
Pethia gelius
Also called Golden barb, Dwarf barb, Puntius gelius (former name), Cyprinus gelius (former name)
From South Asia: the Ganges and Brahmaputra drainages of northern India, Nepal and Bangladesh, with reports from Pakistan and possibly Myanmar.12
At a glance the quick version
Looks how to spot one
Small scaled barb
A tiny, slim barb with a pale golden-yellow body marked by two or three dark blotches and small dark spots near the fin bases. The dorsal, pelvic and anal fins glow a brighter yellow. Females are a little larger and rounder, males more vividly coloured.1
Personality what they are like
Gentle and a little shy. It settles and shows its best colours when kept in a decent-sized group alongside other small, calm fish such as small danios, loaches or dwarf shrimp.1
Daily activity how busy a day looks
An active schooling fish that likes open swimming space plus planted cover to retreat into.1
Grooming and care the hands-on bits
Keep water clean and stable with regular partial water changes; suits a cooler, subtropical tank. Water: about 18-24 C, pH 6.0-7.0, soft to moderately hard (up to about 10-15 dGH).123
Home where they are happiest
A tank with a base of at least about 60 x 30 cm (roughly 54 litres) with soft substrate, plants and gentle flow, reflecting its home in slow, silty streams and river margins.12
Food basics what goes in the bowl
Omnivore that eats small insects, worms and crustaceans in the wild. Accepts small dried foods, ideally with daily small live or frozen foods such as Daphnia and brine shrimp for best colour.12
Company who they like around
A schooling species; keep at least 8-10 together.1
The story where it all began
Described by Francis Hamilton in 1822 from the Ganges region, it was long placed in the genera Cyprinus and Puntius before moving to Pethia. A 2013 study by Knight helped separate it from close look-alikes such as Pethia canius and Pethia aurea.31
Fun facts for the dinner table
- 1
At around 4-5 cm long it is one of the smallest barbs kept in aquariums.1
- 2
It scatters its eggs in very shallow water, around 15 cm deep, and the parents do not guard them.2
- 3
Unlike many tropical barbs, it prefers fairly cool water, roughly 18-24 C.1
- 4
Its natural home is slow, murky streams that pass through farmland, where water depth changes with the seasons.1
Recognised by the official bits
- IUCN Red List
- Least Concern (assessed 2010).2

Owner questions the things everyone asks
How often should I feed my Golden Dwarf Barb?
Feed your Golden Dwarf Barb small amounts once or twice daily. For the best colour, include small live or frozen foods like Daphnia and brine shrimp.12 Furry Diary plan
What does a Golden Dwarf Barb eat, and what should it never eat?
Your Golden Dwarf Barb is an omnivore that enjoys small dried foods and daily live or frozen treats. What it should never eat varies by individual; ask your vet or a good breeder for specific advice.
How much space does a Golden Dwarf Barb need?
A tank with a base of at least 60x30 cm (about 54 litres) is ideal. Keep a school of 8-10 to see their best colours and active behaviour.12
What temperature, light or water does a Golden Dwarf Barb need?
Keep the water at 18-24°C with a pH of 6.0-7.0 and soft to moderately hard hardness. Provide planted cover and gentle flow to mimic their natural home.123
How often should I clean a Golden Dwarf Barb's home?
Furry Diary's starting plan suggests a 25% water change weekly, glass cleaning weekly, and rinsing the filter monthly in old tank water. Regular partial changes keep the water stable and clean.1 Furry Diary plan
Can a Golden Dwarf Barb live with others?
Yes, this gentle schooling fish needs at least 8-10 of its own kind. It can also live with other small calm fish like danios, loaches, or dwarf shrimp.1
How long does a Golden Dwarf Barb live?
The lifespan of a Golden Dwarf Barb varies; ask a good breeder or your vet for more specific information.
Can I handle a Golden Dwarf Barb?
It's best not to handle your Golden Dwarf Barb; they are delicate fish that thrive when observed in their tank.
