The striped barb (Puntius semifasciolatus) is regarded as the ideal tank mate for the Chinese betta (Betta splendens), primarily for the following reasons:
Compatibility
Bettas are generally aggressive, but they rarely attack striped barbs. This is because striped barbs are smaller in size and pose no threat to bettas. Additionally, the two species share a symbiotic relationship in the wild, leading bettas to show a high level of tolerance toward striped barbs.
Environmental Adaptability
Striped barbs are cold-tolerant and hardy, making them well-suited to live with bettas in the same water temperature (approximately 23°C). They also have similar water quality requirements, eliminating the need for additional adjustments to environmental parameters when kept together.
Behavior and Diet
Striped barbs have a gentle temperament and do not compete for food, which reduces conflicts with bettas. Furthermore, the two species have similar dietary preferences, and striped barbs are highly adaptable, resulting in low maintenance difficulty.
Practical Mixed Breeding Results
User tests have shown that when provided with hiding spaces and a sufficiently sized aquarium, the two species can coexist harmoniously. Striped barbs are also affordable and have a high survival rate, making them ideal for pairing with bettas in an aquarium.
Note: When keeping them together, ensure there are hiding places (such as aquatic plants and rocks) in the aquarium and maintain cleanliness to reduce the risk of conflicts.
