Can Uaru and White Cloud Mountain Minnow Live Together?

🔴Not Recommended

Uaru and White Cloud Mountain Minnow are not recommended as tank mates due to no temperature overlap. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

Uaru is a generally mild-mannered species (4/10), while White Cloud Mountain Minnow is peaceful (1/10). This modest difference means Uaru may occasionally assert dominance over White Cloud Mountain Minnow.

Uaru 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

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

Water Parameters

There is no temperature overlap between Uaru (27–30°C) and White Cloud Mountain Minnow (14–22°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–8 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Uaru and White Cloud Mountain Minnow together, plan for an aquarium of at least 480 litres with a minimum length of 150 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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: Driftwood (Digestion/Hiding), Sand (Sifters), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Uaru is a plant destroyer, which conflicts with White Cloud Mountain Minnow's requirement for live plants. Compromise where possible or prioritise the more critical need.

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

Diet & Feeding

Feeding time deserves special attention with this pairing. Uaru is a known shrimp eater and may prey on small invertebrates or nano fish like White Cloud Mountain Minnow.

Frequently Asked Questions

Can Uaru and White Cloud Mountain Minnow live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Uaru and White Cloud Mountain Minnow need?

A minimum of 480 litres (tank length at least 150 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Uaru and White Cloud Mountain Minnow together?

Unfortunately, there is no temperature range that satisfies both species. Uaru requires 27–30°C, while White Cloud Mountain Minnow needs 14–22°C.

Are Uaru or White Cloud Mountain Minnow aggressive?

Uaru is generally mild-mannered (4/10) and White Cloud Mountain Minnow is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Uaru and White Cloud Mountain Minnow need?

Both species overlap in the 6–7 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
