Black Ruby Barb – Pethia nigrofasciata
The Black Ruby Barb is a striking freshwater fish prized for its deep, ruby-red coloration, which intensifies as males mature, contrasted by a dark black stripe along the body. Active and hardy, these barbs add both color and energy to community aquariums.
Black Ruby Barbs are schooling fish and thrive in groups of 6 or more. While generally peaceful, males can display mild territorial behavior during breeding, making them best suited for lively, well-planted tanks.
