Food and feeding

Golden barbs (Puntius gelius) are omnivorous and not picky eaters. They will readily accept high-quality flakes, micro pellets, and granules. To maintain their health and coloration, regularly supplement their diet with live or frozen foods such as daphnia, brine shrimp, or bloodworms. Occasional feedings of blanched vegetables (like spinach or zucchini) are also beneficial. Feed small portions 1–2 times daily.

Origin

This species is native to South Asia and is found in the slow-moving rivers, streams, and rice paddies of India, Pakistan, and Bangladesh. They thrive in shallow, densely planted environments with soft to moderately hard water.

Sexing

Males tend to be slimmer and display more intense coloration, with a pronounced dark vertical stripe along the side. Females are slightly rounder, especially when gravid, and may have a paler appearance.

Breeding

Golden barbs are egg scatterers and can be bred in a small separate tank. Use fine-leaved plants or spawning mops to catch the eggs, and maintain soft, slightly acidic water with a temperature around 24 °C (75 °F). Spawning usually occurs in the early morning. After the eggs are laid, promptly remove the adults to avoid egg predation. Eggs typically hatch in 24–36 hours, and fry become free-swimming within 2–3 days. Feed them infusoria or liquid fry food, followed by newly hatched brine shrimp as they grow.

Lifespan

Puntius gelius has a relatively short lifespan, averaging 2 to 3 years under good aquarium conditions.

Short description

The golden barb is a small, peaceful and active schooling fish that brings vibrant color and motion to community aquariums. Best kept in groups of at least five, they are social fish that feel more secure and exhibit natural behavior when in a shoal. Their shimmering golden body and contrasting black stripe make them stand out in planted tanks. A calm environment with moderate lighting and good water quality helps them thrive.

Suitable tankmates

Golden barbs are ideal for peaceful community aquariums with similarly sized fish. Compatible tankmates include:

Harlequin rasboras
Pygmy corydoras
Zebra danios
Ember tetras
Honey gouramis
Other small, peaceful barbs and characins

Recommended plants

Golden barbs do well in planted tanks with moderate to dense vegetation. Plants offer security, spawning sites, and help maintain water quality. Ideal plant species include:
