Can Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) Live Together?
Keeping Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 46 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Malaysian Trumpet Snail (MTS) is a peaceful species (0/10), while Shell Dweller (Multi) is moderately assertive (6/10). This notable difference means Shell Dweller (Multi) may occasionally assert dominance over Malaysian Trumpet Snail (MTS).
Large aggression gap (6 points) between Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) increases stress risk for the more peaceful fish.
Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) 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.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
Water Parameters
The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
Both fish can tolerate a pH between 7.8 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 10–25 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) together, plan for an aquarium of at least 46 litres with a minimum length of 45 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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, Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while Shell Dweller (Multi) requires Sand (Sifters). 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.

What water temperature is best for Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) together?▾
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Malaysian Trumpet Snail (MTS) or Shell Dweller (Multi) aggressive?▾
Malaysian Trumpet Snail (MTS) is peaceful (0/10) and Shell Dweller (Multi) is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Malaysian Trumpet Snail (MTS) and Shell Dweller (Multi) need?▾
Both species overlap in the 7.8–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Shell Dweller (Multi)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Shell Dweller (Multi) 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 Malaysian Trumpet Snail (MTS) being nocturnal affect compatibility?▾
Malaysian Trumpet Snail (MTS) 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 Malaysian Trumpet Snail (MTS) during evening hours.
