Black Ruby Barb - (No Online Purchases)

Scientific Name: Pethia nigrofasciata (formerly Puntius nigrofasciatus)

Description: A beautiful and active freshwater fish known for its striking colouration. Mature males develop a deep ruby-red to purple body with dark vertical bands, particularly during breeding, while females display more subdued golden-brown tones. Black Ruby Barbs are peaceful, energetic schooling fish that make an attractive addition to well-planted community aquariums.

Origin: Sri Lanka, where they inhabit shaded, slow-moving forest streams and freshwater waterways.

pH: Approximately 6.0–7.5

Temperature: Around 22–27°C

Adult Size: Approximately 5–6 cm

Lifespan: Approximately 5–7 years

Food: Omnivorous. Feed quality tropical flakes, small pellets, spirulina-based foods and occasional frozen or live foods such as bloodworms, brine shrimp and daphnia. A varied diet helps maintain healthy colouration and growth.

Compatibility: Generally peaceful and suitable for community aquariums with similarly sized, non-aggressive fish. Good tank mates include Tetras, Rasboras, Danios, peaceful Gouramis and Corydoras. Best kept in groups of at least six, preferably eight or more, to encourage natural schooling behaviour and reduce occasional fin-nipping.

Habitat: A well-planted freshwater aquarium with driftwood, shaded areas and open swimming space. Black Ruby Barbs prefer clean, well-oxygenated water with gentle to moderate flow. Dark substrates and natural planting help bring out their beautiful ruby colouration. Regular water changes and stable water conditions are essential.
