Can White Cloud Mountain Minnow and Yellow Lab (Mbuna) Live Together?
White Cloud Mountain Minnow and Yellow Lab (Mbuna) 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.
At a Glance
Behaviour & Temperament
White Cloud Mountain Minnow is a peaceful species (1/10), while Yellow Lab (Mbuna) is moderately assertive (6/10). This notable difference means Yellow Lab (Mbuna) may occasionally assert dominance over White Cloud Mountain Minnow.
White Cloud Mountain Minnow and Yellow Lab (Mbuna) 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.
Water Parameters
There is no temperature overlap between White Cloud Mountain Minnow (14–22°C) and Yellow Lab (Mbuna) (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.
Both fish can tolerate a pH between 7.5 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 10–20 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house White Cloud Mountain Minnow and Yellow Lab (Mbuna) together, plan for an aquarium of at least 180 litres with a minimum length of 90 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: Plants - Densely covered, Smooth Gravel (Sensitive Barbels), Sand (Sifters). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Yellow Lab (Mbuna) 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 moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.
What size tank do White Cloud Mountain Minnow and Yellow Lab (Mbuna) need?▾
A minimum of 180 litres (tank length at least 90 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 White Cloud Mountain Minnow and Yellow Lab (Mbuna) together?▾
Unfortunately, there is no temperature range that satisfies both species. White Cloud Mountain Minnow requires 14–22°C, while Yellow Lab (Mbuna) needs 24–28°C.
Are White Cloud Mountain Minnow or Yellow Lab (Mbuna) aggressive?▾
White Cloud Mountain Minnow is peaceful (1/10) and Yellow Lab (Mbuna) is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do White Cloud Mountain Minnow and Yellow Lab (Mbuna) need?▾
Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Yellow Lab (Mbuna)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Yellow Lab (Mbuna) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
