Can False Rummy-Nose Tetra and Malaysian Trumpet Snail (MTS) Live Together?

False Rummy-Nose Tetra is a peaceful species (1/10), while Malaysian Trumpet Snail (MTS) is peaceful (0/10). This modest difference means False Rummy-Nose Tetra may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

In terms of spatial distribution, False Rummy-Nose Tetra prefers the Middle (Open Water) zone, whereas Malaysian Trumpet Snail (MTS) occupies the Bottom (Substrate) zone. 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.

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 8–12 dGH. Regular testing will ensure conditions stay within this range.

To house False Rummy-Nose Tetra and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 80 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, Leaf Litter/Blackwater, Sand (Sifters), Soil / Nutrient Rich. 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.
