Black Ruby Barb (Pethia nigrofasciata) for Sale in Canada

The Black Ruby Barb (Pethia nigrofasciata) is a beautiful freshwater schooling fish admired for its dramatic dark body, ruby-red coloration, and peaceful personality. Native to Sri Lanka, this species is one of the most attractive smaller barbs for planted community aquariums.

Mature males can develop an intense ruby-red coloration, particularly when displaying or in breeding condition. Their dark vertical markings provide a striking contrast against the red tones, creating an elegant appearance that changes with mood, age, and aquarium conditions.

Black Ruby Barbs are active without being excessively boisterous, making them a versatile choice for a peaceful community aquarium. They look particularly impressive when maintained in a proper group among dense aquatic plants and natural décor.
