Can Chinese Barb (Green Barb) and White Cloud Mountain Minnow Live Together?

Chinese Barb (Green Barb) is a peaceful species (2/10), while White Cloud Mountain Minnow is peaceful (1/10). This modest difference means Chinese Barb (Green Barb) may occasionally assert dominance over White Cloud Mountain Minnow.

Chinese Barb (Green Barb) and White Cloud Mountain Minnow both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Worth noting: White Cloud Mountain Minnow is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 16°C and 22°C. Aim for the midpoint of this range (around 19.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.

To house Chinese Barb (Green Barb) and White Cloud Mountain Minnow together, plan for an aquarium of at least 75 litres with a minimum length of 80 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
