Can Bladder Snail (Pest Snail) and Malaysian Trumpet Snail (MTS) Live Together?

Both Bladder Snail (Pest Snail) and Malaysian Trumpet Snail (MTS) are peaceful species with an aggression score of 0/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Bladder Snail (Pest Snail) and Malaysian Trumpet Snail (MTS) 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.

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 30°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 8–20 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Bladder Snail (Pest Snail) and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 6 litres with a minimum length of 15 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: Established Algae (Otocinclus), Sand (Sifters), Soil / Nutrient Rich. Meeting these requirements will help both species thrive.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
