As adults, Rosy Barbs may eat their own eggs, so it’s important to separate them if you want to raise the fry. FishLore is a valuable resource for aquarists looking for information on Rosy Barbs.

It provides detailed descriptions of each species in terms of size, temperament, feeding habits, breeding habits, as well as common and scientific names.


Rosy Barbs are a species of freshwater fish known by many different names in different countries. They have been referred to as the “chikka karso” in Kannada, “pothia sidre” in Nepal, and “kanchan punti” in Bengal.

These fish make for a great beginner fish as they are small, easy to care for, and thrive in cold water. Rosny Barbs require a water temperature of 65°F to 78°F and a water hardness of 5 to 15 dH.

They are an omnivorous feeder, feeding on zooplankton, phytoplankton, crustaceans, aquatic plants, and bloodworms. They can grow up to 4 inches long and make a rewarding aquarium fish if cared for properly.

Origin and Distribution

The Rosy barb is native to the eastern Indian and western Pacific Ocean regions. The scientific name of the species is Pethia Conchonius, but they are commonly known as red barbs or rosy barbs.

The rosy barb can be found in the freshwater aquariums of countries all over the world, including Singapore, Mexico, Puerto Rico, Australia, and Colombia.

The rosy barb from West Bengal tends to be intensely colored and have reflective scales, whereas specimens from Assam tend to be not as rich in coloration.

Outwardly, rosy barbs look similar to other barb species, with a long body and pectoral fins that are made up of sharp points. However, rosy barbs have a distinctive red shade on their bodies.

Colors and Markings

The male Rosy barb has vivid red coloration, while females tend to have a duller gold, olive, or yellow color with little to no red.

A large black blotch appears on the caudal peduncle near the tail of the fish. Females are generally smaller and fatter and more yellow in color than males, which are typically more slender and with brighter coloring.

The rose gold or orange color of male Rosy Barb is distinct from female Rosy Barbs, which are solid gold. The distinctive patterns make it easy for aquarists to identify the species in aquariums.

Gender Differences

The aquarium size of 30 gallons or larger is ideal for keeping rosy barb fish in a community setting.

These fish flourish in aquariums with plenty of plant matter and hiding places as they enjoy spending time near the bottom of the aquarium.

Breeding the Rosy Barb

Rosy barb fish are easy to breed in captivity with a ratio of one male to two females. They can be easily provided with broad-leaf plants to give the female a place to scatter its eggs.

The eggs and fry should be protected from predators such as aggressive fish species, as well as from temperature fluctuations and low oxygen conditions. When the eggs hatch, the fry can be fed baby brine shrimp.

The rosy barb can be crossbred with other species to create androgenetic offspring that inherit all of their nuclear genetic material from the male rosy barb. These fish are a valuable addition to aquariums as they can live up to six years and enjoy being kept as community fish, typically preferring peaceful tank mates such as smaller cichlids.

Sexual dimorphism

Rosy barb species display sexual dimorphism, with females being smaller and plumper than males.

Males, on the other hand, typically have larger heads and fins and more colorful bodies. They also have a black patch on their dorsal fins, which is unique to the species.
