Care Guide:

Scientific Name: Gastromyzon zebrinus
Common Name: Zebra Hillstream Loach
Family: Balitoridae
Origin: Native to the fast-flowing rivers and streams of Borneo.

1. Water Parameters:

• Temperature: 68°F to 75°F (20°C to 24°C)
• pH Range: 6.5 to 7.5
• Water Hardness: Soft to moderate (4-10 dGH)
• Flow: High water flow to mimic their natural riverine habitat.

Note: These loaches thrive in well-oxygenated water with consistent parameters. Regular water changes and strong filtration are essential.

2. Tank Setup:

• Minimum Tank Size: 20 gallons for a small group of 3-5 loaches.
• Substrate: Smooth gravel or sand substrate to mimic riverbeds and protect their delicate undersides.
• Decor: Incorporate smooth river rocks, driftwood, and slate to provide grazing surfaces and hiding spots. Plants such as Anubias, Java fern, or mosses can be attached to rocks or wood for natural decor.
• Flow and Filtration: Use a powerhead or canister filter to create strong currents and maintain high oxygen levels.
• Lighting: Moderate lighting to encourage natural algae growth, which serves as a food source.

3. Feeding:

Zebra Hillstream Loaches are omnivores with a strong preference for algae and biofilm, but they require a balanced diet for optimal health.

• Primary Diet: Algae wafers, sinking pellets, and blanched vegetables like zucchini or spinach.
• Supplementary Foods: Protein-based foods such as frozen bloodworms, daphnia, or brine shrimp.
• Feeding Schedule: Feed small amounts 1-2 times daily, ensuring they have access to natural grazing surfaces.

Tip: Allow algae to grow on rocks and decor as a natural food source for your loaches.

4. Tank Mates:

Zebra Hillstream Loaches are peaceful and can thrive in community tanks with similarly sized, non-aggressive species.

• Compatible Tank Mates: Small, peaceful fish such as danios, rasboras, tetras, or other loaches (e.g., Kuhli loaches). Shrimp species like Amano or Cherry Shrimp are also suitable.
• Tank Mate Cautions: Avoid housing them with large or aggressive fish that may outcompete them for food or harm them.

5. Behavior and Temperament:

• Activity Level: Active and engaging, Zebra Hillstream Loaches are constantly on the move, grazing on surfaces and exploring their environment.
• Social Behavior: They are social fish that do best in small groups of 3 or more. They can exhibit playful interactions but are generally non-aggressive.

6. Breeding:

Breeding Zebra Hillstream Loaches in captivity is rare and challenging. They are egg scatterers, and successful spawning often requires closely mimicking their natural riverine conditions with temperature fluctuations and seasonal cues.

Health and Maintenance:

Zebra Hillstream Loaches are hardy but sensitive to poor water quality and low oxygen levels. Regular maintenance, including weekly water changes (20-30%), is essential to keep their environment pristine. Monitor for signs of stress or illness, such as lethargy or loss of appetite.

Key Care Tips:

• Maintain strong water flow and high oxygenation.
• Provide smooth surfaces for grazing and hiding.
• Offer a diet rich in algae and supplemented with protein.
• Keep them in a group to promote natural behaviors.

With their striking stripes and dynamic behavior, the Zebra Hillstream Loach will add both visual appeal and ecological balance to your aquarium. Perfect for aquarists seeking an active and functional species for a biotope-inspired setup!
