Pseudogastromyzon fasciatus - Zebra Hillstream loach, Chinese Hillstream loachPseudogastromyzon fasciatus - Zebra Hillstream loach, Chinese Hillstream loachPseudogastromyzon fasciatus - Zebra Hillstream loach, Chinese Hillstream loach
  • Scientific name: Pseudogastromyzon fasciatus
  • Synonyms: Psilorhynchus fasciatus, Pseudogastromyzon fasciatus fasciatus, Pseudogastromyzon fasciatus jiulongjiangensis
  • Common name: Zebra Hillstream loach, Chinese Hillstream loach
  • Group: Loaches
  • Habitat: Asia; China
  • Size: 7-8 cm
  • Biotope: Found in shallow, fast-flowing, highly-oxygenated hillstreams over the rocky substrate.
  • Social behavior: Peaceful, can be kept in a community tank. It should be kept in small groups.
  • Diet: Omnivorous; in nature they eat algae and micro-organisms, sometimes insect larvae. In aquarium they accept good-quality dried foods, especially spirulina.
  • Breeding: Rare in aquarium.
  • Tank: Minimum 100 litres
  • Population: 4-5 fish for 100 litres
  • Decoration: Most importantly the water must be clean and well-oxygenated. The tank should have a good filter with fast current (20 times of the water volume per hour). Use gravel substrate, with some larger rocks and pebbles. Roots or driftwood branches can be added to the tank with Java fern or Anubias attached on them. Lighting should be bright to encourage algae growth in the aquarium.
  • Temperature: 20-24 °C
  • pH: 7-8
  • Hardness: 1-12 NK°
  • Lifespan: 8 years

Description: Zebra Hillstream loach can be easily distingusihed from other Hillstream loaches by its body size and pattern. The head is marked with dark spots back to the pectoral fins, with up to 3 dark vertical stripes just behind and below the eye, running to the snout. Pseudogastromyzon fasciatus has a yellowish to light brown body color with multiple dark vertical bars along the entire length. The yellow dorsal fin has a broad dark band while the anal, pectoral, and pelvic fins have a poorly defined dark band. The caudal fin has 2-3 broad, oblique dark bands. Their bodies are specialized to exist in high-current areas, where they live amongst rocks and driftwood. The adult body shape is flattened, with the overlapping pectoral and pelvic fins spread out to the sides like butterfly wings. They are not recommended for beginners because of their need for clear water and as they do not have scales, it make them more prone to disease and very sensitive to medications used to treat disease.

Males have a more slimmer form when viewed from above. There are occasional reports of aquarium spawnings but a precise method for successful breeding has yet to be established. Presumably these fish are a seasonal and possibly migratory spawner in nature.
