Parazacco "Meizhou" (Predaceous Chub variant) – ~13 cm

A slender East Asian minnow known for its elongated body, gentle dorsal arch, pale brown back with reddish side accents, white belly, and a distinctive dark spot at the base of the tail fin. These traits match the Parazacco spilurus species, which is found across parts of China and Vietnam. 

Habitat & Behavior:
Naturally inhabits small, subtropical freshwater streams and rivers—occasionally in mildly brackish water—typically in benthopelagic zones (mid to near-bottom water layers).  Most populations have an IUCN status listed as Data Deficient, though its synonym Parazacco fasciatus is considered of Least Concern. 

Size:
Maxes out around 13.4 cm standard length, based on recorded specimens. 

Tank Setup:

• Size: A 60–80 L (~15–20 gal) aquarium is appropriate for small groups—more space is ideal for natural behavior.

• Decor: Provide smooth substrate, rocks, and moderate planting to mimic stream environments.

• Flow & Filtration: Gentle, clear water flow with good filtration and oxygenation.

Water Conditions:

• Keep in temperate water (around 20–24 °C).

• Maintain neutral pH and moderate water hardness, aiming for clarity.

Diet:
An omnivorous and active feeder—accepts high-quality flakes or micro pellets, plus live or frozen additions like daphnia, brine shrimp, or bloodworms.

Behavior & Tankmates:

• Generally peaceful but may become shy if outnumbered or overcrowded—best kept in schools of 6+.

• Compatible with other small, peaceful freshwater species like danios, rasboras, or small barbs.
