Can Malaysian Trumpet Snail (MTS) and Pacific Sturgeon Live Together?

Malaysian Trumpet Snail (MTS) is a peaceful species (0/10), while Pacific Sturgeon is generally mild-mannered (3/10). This modest difference means Pacific Sturgeon may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

Malaysian Trumpet Snail (MTS) and Pacific Sturgeon both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

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 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 Pacific Sturgeon together, plan for an aquarium of at least 20000 litres with a minimum length of 600 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: Sand (Sifters), Soil / Nutrient Rich, 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 Pacific Sturgeon requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while Pacific Sturgeon requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Compromise where possible or prioritise the more critical need.

Malaysian Trumpet Snail (MTS) prefers Low (Still Water) flow while Pacific Sturgeon needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Malaysian Trumpet Snail (MTS) and Pacific Sturgeon are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Feeding time deserves special attention with this pairing. Pacific Sturgeon is a known shrimp eater and may prey on small invertebrates or nano fish like Malaysian Trumpet Snail (MTS).

Because Pacific Sturgeon is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Malaysian Trumpet Snail (MTS) receives an adequate share.
