Can Clown Pleco (L104) and White Cloud Mountain Minnow Live Together?
Clown Pleco (L104) 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.
At a Glance
Behaviour & Temperament
Clown Pleco (L104) is a generally mild-mannered species (3/10), while White Cloud Mountain Minnow is peaceful (1/10). This modest difference means Clown Pleco (L104) may occasionally assert dominance over White Cloud Mountain Minnow.
In terms of spatial distribution, Clown Pleco (L104) prefers the Bottom (Substrate) zone, whereas White Cloud Mountain Minnow occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
Worth noting: Clown Pleco (L104) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, White Cloud Mountain Minnow is a known jumper, so a tight-fitting lid is essential.
Water Parameters
There is no temperature overlap between Clown Pleco (L104) (23–28°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 7.8. 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. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Clown Pleco (L104) and White Cloud Mountain Minnow together, plan for an aquarium of at least 90 litres with a minimum length of 60 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), 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.

Frequently Asked Questions
Can Clown Pleco (L104) 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 Clown Pleco (L104) and White Cloud Mountain Minnow need?▾
A minimum of 90 litres (tank length at least 60 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 Clown Pleco (L104) and White Cloud Mountain Minnow together?▾
Unfortunately, there is no temperature range that satisfies both species. Clown Pleco (L104) requires 23–28°C, while White Cloud Mountain Minnow needs 14–22°C.
Are Clown Pleco (L104) or White Cloud Mountain Minnow aggressive?▾
Clown Pleco (L104) is generally mild-mannered (3/10) and White Cloud Mountain Minnow is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Clown Pleco (L104) and White Cloud Mountain Minnow need?▾
Both species overlap in the 6–7.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Clown Pleco (L104)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Clown Pleco (L104) 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.
Does Clown Pleco (L104) being nocturnal affect compatibility?▾
Clown Pleco (L104) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Clown Pleco (L104) during evening hours.
