Black Ruby Barb - Pethia nigrofasciata 2-3cm
The Black Ruby Barb (Pethia nigrofasciata) is a vibrant and active fish native to the rivers and streams of Sri Lanka. Known for its striking black and red coloration, this barb is a popular choice for community tanks. Black Ruby Barbs are generally peaceful and do best in groups of six or more, as they are schooling fish and feel more secure in numbers.

A dark substrate can enhance their colors, making them even more visually appealing. These barbs are omnivores and will eat a variety of foods, including high-quality flake food, small live foods, and frozen foods. Their active nature and vibrant appearance make them a delightful addition to a community tank, provided the tank mates are also peaceful and the environment is well-maintained.

They are also known for their hardiness and adaptability, making them a reliable and enjoyable fish to keep in a home aquarium.
