Black Ruby Barb – Pethia nigrofasciata
Introduction:
The Black Ruby Barb (Pethia nigrofasciata), named for its striking ruby-red coloration during maturity, is a small, active species that typically grows up to 2.5 inches. Originating from the clear streams of Sri Lanka, this hardy fish is a favorite for both beginner and experienced hobbyists looking for vibrant additions to their community tanks.
1. Natural Habitat and Behavior
- Natural Habitat: Black Ruby Barbs are found in the slow-moving, shaded streams of Sri Lanka, where vegetation and submerged roots offer ample hiding spaces.
- Behavior: They are peaceful, schooling fish best kept in groups of at least six. These barbs are lively and interact well within a community setup, showing brighter colors when kept in groups.
2. Aquarium Setup
- Tank Size: A minimum of 20 gallons for a small school, with more space enhancing group dynamics and color vibrancy.
- Substrate: A soft, sandy substrate with areas of fine gravel replicates their natural habitat.
- Decor: Use live plants, driftwood, and rocks to provide hiding spots, while leaving open swimming areas.
- Water Conditions: Ideal temperatures range from 72°F to 79°F, with a pH of 6.0 to 7.5. Soft to moderately hard water is suitable.
- Lighting: Moderate lighting mimics their natural environment and prevents stress, while showcasing their beautiful coloration.
3. Diet and Feeding
- Diet: Black Ruby Barbs are omnivores. Provide high-quality flakes, pellets, and a variety of frozen or live foods, including brine shrimp, daphnia, and bloodworms.
- Feeding Schedule: Feed them twice daily, ensuring a varied diet to maintain optimal health and color.
4. Compatibility with Other Fish
- Compatible Species: Ideal tank mates include other peaceful species like tetras, rasboras, danios, and small cichlids. They do well in community tanks with similarly sized, non-aggressive fish.
- Incompatible Species: Avoid slow-moving or long-finned fish, as Black Ruby Barbs can be fin nippers, particularly if kept in too small a group.
5. Common Challenges and Tips
- Group Size: Keeping Black Ruby Barbs in groups helps reduce stress and encourages natural behavior, including vibrant displays during mating.
- Water Quality: Regular water changes are necessary, as these barbs prefer clean water. Weekly maintenance will keep them healthy and active.
- Color Enhancement: Males show brighter colors, especially during mating season. A varied diet and the presence of other males can intensify these hues.
Conclusion:
The Black Ruby Barb is a colorful, active, and peaceful choice for community aquariums. With their vibrant colors, especially in groups, and their adaptability to different setups, they bring dynamic beauty to any tank. With the right care, tank mates, and diet, Black Ruby Barbs will thrive and enchant in freshwater aquariums.
