Black Ruby Barbs

The black ruby barb (Pethia nigrofasciata, formerly Puntius nigrofasciatus) or purplehead barb is a tropical cyprinid fish endemic to Sri Lanka, where it occurs in forested streams from the Kelani basin to the Nilwala basin. They are found in streams on hills around 1000 ft in elevation.

This species is good for keeping with other barbs and similar fish. In captivity, the fish are omnivorous, with a healthy appetite. The black ruby barb is an active swimmer that is best kept in schools of at least six. House in a well-planted aquarium, with shading from surface weed or floating plants. They may nibble in fine-leaved plants, so choose plants with care.

Are Black Ruby Barbs aggressive?
Barbs can be a bit aggressive in small groups as a general rule. Their stress from being isolated almost always comes out as aggression towards their tankmates. Keep Black Ruby barbs in groups of 6 or more to appease aggressive behaviour.
