Rosy Barb

A legendarily durable fish, often recommended to beginning aquarium hobbyists. Aaron Norman


Here is a legendarily hardy fish, ideal for beginners. It is durable, easy to feed and brings nice action to any tank when kept in a school. During spawning, the male becomes deep red. Long-finned varieties have been developed and are often available.

Family: Cyprinidae

Other common name(s):

Native range:

Habitat: As with most of the Barbs, decor is strictly for the aquarist, as are plants, which can be restricted to the sides and back of the tank. They need lots of open swimming space, which is easier to provide in a longer, rather than tall, aquarium. Because the Rosy Barb may root around in the gravel, a fine-grade substrate is best. Darker colors (substrate and background) well help show off the fish’s colors and make them feel more secure.

Maximum length: 14 cm (6 in)

Minimum aquarium size: 76 L (20 gal)

Water: Freshwater 22 °C (72 °F) - 26 °C (79 °F)

General swimming level: Midwater


Omnivore. The Rosy Barb will accept most commercial meaty and vegetable-based aquarium fare, including good-quality Spirulina flakes, algae wafers and color-enhancing rations.

Aquarium Compatibility

The Rosy Barb is not quite as rambunctious as the Tiger Barb. This is a schooling species that should be kept in groups of at least three. Rowdy cichlids or lone tiger barbs may harass them.


Great species for beginning breeders. If a group of Rosy Barbs is well fed and kept with clumps of bushy plants, spawning events are almost inevitable.


The Rosy Barb is one of the more durable barbs and is tolerant of cooler water temperatures.
