The rosy barb (Pethia conchonius) is a subtropical freshwater cyprinid fish found in southern Asia from Afghanistan to Bangladesh.

In the wild their omnivorous diet consists of worms, insects, crustaceans, and plant matter.

Rosy barbs natively live in lakes and fast flowing water in a subtropical climate.

Spawning usually occurs in the early morning, and lasts several hours resulting in several hundred eggs.

A day later, the young fish will hang on the plants, and/or the sides of the tank if the breeding takes place in an aquarium.

It is considered one of the hardiest barbs, undemanding and beautiful, and most impressively colored during the mating period.
