Butterfly Hillstream Loach – Beaufortia kweichowensis
Introduction:
The Butterfly Hillstream Loach (Beaufortia kweichowensis) is a fascinating freshwater species popular among aquarium hobbyists for its unique appearance and behavior. Reaching up to 3 inches (7.5 cm) in length, this loach is known for its flattened body and wing-like pectoral fins, which help it cling to rocks in fast-flowing streams. Its peaceful nature and algae-grazing habits make it a functional and attractive addition to a well-maintained aquarium.
1. Natural Habitat and Behavior
Native to the fast-moving streams and rivers of China, the Butterfly Hillstream Loach thrives in cool, oxygen-rich waters with rocky substrates. It exhibits a natural tendency to cling to smooth surfaces using its suction-like belly. These loaches are primarily bottom dwellers and are known for their shy but peaceful demeanor, often observed grazing on algae or biofilm.
2. Aquarium Setup
- Tank Size: Minimum 20 gallons (76 liters) for a small group.
- Substrate: Smooth river rocks and fine sand to mimic its natural habitat.
- Decor: Add driftwood, rounded stones, and plants such as Java moss or Anubias. These provide shelter and promote the growth of biofilm.
- Water Conditions:
- Temperature: 68–75°F (20–24°C)
- pH: 6.5–7.5
- Hardness: 5–12 dGH
- Strong water flow with high oxygen levels is essential. Use a powerhead or strong filter to simulate stream-like conditions.
- Lighting: Moderate to high lighting to support algae growth.
3. Diet and Feeding
The Butterfly Hillstream Loach is primarily an herbivore but benefits from a varied diet:
- Primary Food: Algae and biofilm in the tank.
- Supplements: Blanched vegetables (zucchini, spinach) and algae wafers.
- Occasional Treats: Protein sources like daphnia or brine shrimp.
Feed small amounts twice daily to prevent overfeeding and maintain water quality.
4. Compatibility with Other Fish
Butterfly Hillstream Loaches are peaceful and thrive in community tanks. Ideal tank mates include:
- Other non-aggressive species like neon tetras, rasboras, and guppies.
- Bottom-dwellers such as Corydoras catfish and small Plecos.
- Avoid territorial or aggressive fish, which can stress these loaches.
It’s best to keep them in groups of at least three to encourage natural behaviors and reduce shyness.
5. Common Challenges and Tips
- Water Quality Sensitivity: Regular water changes are crucial as these loaches are highly sensitive to poor water conditions.
- Temperature Control: Avoid high temperatures, as they mimic cooler mountain streams.
- Shyness: Provide plenty of hiding spots to make them feel secure.
- Algae Growth: Maintain some algae in the tank, but avoid letting it overrun the environment.
Conclusion
The Butterfly Hillstream Loach is a captivating and beneficial addition to aquariums, especially for those seeking an algae-grazing species with unique aesthetics. With proper care and attention to their natural habitat requirements, these loaches will thrive and add dynamic activity to your tank.
