Can Malaysian Trumpet Snail (MTS) and White Cloud Mountain Minnow Live Together?

Malaysian Trumpet Snail (MTS) is a peaceful species (0/10), while White Cloud Mountain Minnow is peaceful (1/10). This modest difference means White Cloud Mountain Minnow may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

In terms of spatial distribution, Malaysian Trumpet Snail (MTS) 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.

Worth noting: Malaysian Trumpet Snail (MTS) 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.

The safe temperature window for both species falls between 18°C and 22°C. Aim for the midpoint of this range (around 20.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 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 8–20 dGH. Regular testing will ensure conditions stay within this range.

To house Malaysian Trumpet Snail (MTS) and White Cloud Mountain Minnow together, plan for an aquarium of at least 38 litres with a minimum length of 45 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

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

Note a potential conflict in setup requirements: Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while White Cloud Mountain Minnow requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Malaysian Trumpet Snail (MTS) and White Cloud Mountain Minnow need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
