Parazacco fasciatus – Freshwater Asian Minnow (~13 cm)

A slender, laterally compressed minnow with a slightly downturned mouth and a tapered body. Typically found in clear streams, it's distinguished by a subtle lateral band and a dark spot at the base of its forked tail. It closely resembles Parazacco spilurus, as they're now considered the same species. 

Natural Habitat:
Native to small, benthopelagic (mid-to-bottom) zones of freshwater streams across southern China and Vietnam. It thrives in clear, oxygen-rich waters at low elevations. 

Conservation Status:
Assessed as Least Concern, indicating stable wild populations. It was previously grouped under P. spilurus, classified as Data Deficient. 

Care Guidelines:

• Tank Setup:

  • Ideal for a 60–80 L (~15–20 gal) setup for a small group.

  • Use fine gravel or sand, with driftwood or rocks for structure; soft planting is optional.

  • Maintain gentle to moderate water flow with good filtration and high oxygenation.

• Water Conditions:

  • Temperature: ~20–24 °C (temperate range).

  • pH: Neutral to slightly acidic/alkaline; moderate hardness—mimicking stable stream environments.

• Diet:

  • Omnivorous and adaptable: eats high-quality flakes or micro-pellets, plus live/frozen daphnia, brine shrimp, or bloodworms.

• Behavior & Tankmates:

  • Peaceful schooling fish—best kept in groups of 6 or more to reduce stress.

  • Compatible with other small, non-aggressive tankmates like danios, rasboras, or small barbs.
