Yunnanilus cruciatus

Yunnanilus cruciatus, commonly known as the Vietnamese multi-banded zebra loach, is a delightful species endemic to Vietnam. This small freshwater fish typically reaches a maximum size of approximately 3.4 centimeters (1.3 inches) in standard length. The unique appearance of Yunnanilus cruciatus features striking horizontal bands that resemble a zebra pattern, making it an attractive addition to any aquarium. Its slender body is well-adapted to its natural habitat, where it navigates through dense aquatic vegetation and sandy substrates.

In the wild, Yunnanilus cruciatus inhabits relatively still, shallow stretches of rivers, where it prefers environments rich in aquatic plants. This species thrives in muddy or sandy substrates, allowing it to forage for food and hide from potential predators. The loach’s natural behavior includes burrowing and sifting through the substrate, which helps maintain a balanced ecosystem in its habitat. Its peaceful temperament and schooling behavior make it a favorite among aquarists.

Yunnanilus cruciatus is known for its active nature, often seen darting around the tank, and it exhibits social interactions with its own kind. These fish prefer to live in groups, which reduces stress and promotes natural behaviors. This species is relatively hardy, making it suitable for beginners and experienced aquarists alike. With proper care and conditions, the Vietnamese multi-banded zebra loach can thrive in a well-maintained aquarium, adding both movement and color to the underwater landscape.

Overall, Yunnanilus cruciatus is not only visually appealing but also plays an essential role in maintaining the health of aquatic environments. Its adaptability to aquarium life combined with its charming personality makes it an excellent choice for importers and wholesalers looking to diversify their offerings.

To successfully care for Yunnanilus cruciatus, maintain water parameters within the ideal range. The recommended temperature is between 22°C to 26°C, with a pH of 6.0 to 7.5. While this species is tolerant of various water conditions, stability is crucial for their well-being. A minimum tank size of 50 liters is suggested to provide adequate swimming space and environment complexity.

Feeding Yunnanilus cruciatus is straightforward as they are omnivores. A varied diet consisting of high-quality flake food, sinking pellets, and occasional live or frozen foods such as brine shrimp or bloodworms will keep them healthy and vibrant. Ensure that they receive small portions multiple times a day rather than large quantities to prevent overfeeding.

In terms of compatibility, these loaches are peaceful and can be housed with other small, non-aggressive fish species. However, avoid keeping them with very large or territorial fish that may intimidate or harm them. Acclimation should be done gradually to minimize stress; floating the bag in the tank for about 15 minutes before releasing the fish is recommended. Quarantine new arrivals for at least two weeks to monitor for any signs of disease before adding them to the main tank.

Yunnanilus cruciatus is suitable for shipping due to its hardy nature. When packing, a density of 10-15 fish per liter is recommended to ensure their well-being during transit. Maintain a temperature range of 20°C to 24°C to prevent stress. This species is not listed on CITES, simplifying export regulations.
