Can Malaysian Trumpet Snail (MTS) and Paradise Fish Live Together?
Keeping Malaysian Trumpet Snail (MTS) and Paradise Fish together is possible but requires caution due to differing aggression levels. Provide a spacious tank of at least 90 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 Paradise Fish is semi-aggressive (8/10). This notable difference means Paradise Fish may occasionally assert dominance over Malaysian Trumpet Snail (MTS).
Large aggression gap (8 points) between Malaysian Trumpet Snail (MTS) and Paradise Fish increases stress risk for the more peaceful fish.
In terms of spatial distribution, Malaysian Trumpet Snail (MTS) prefers the Bottom (Substrate) zone, whereas Paradise Fish 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, Paradise Fish is a known jumper, so a tight-fitting lid is essential.
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 Paradise Fish 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. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
Water Parameters
The safe temperature window for both species falls between 18°C and 26°C. Aim for the midpoint of this range (around 22.0°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 8–25 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 Paradise Fish together, plan for an aquarium of at least 90 litres with a minimum length of 80 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, Plants - Densely covered, Plants - Floating. 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.

What water temperature is best for Malaysian Trumpet Snail (MTS) and Paradise Fish together?▾
Keep the aquarium between 18°C and 26°C. A target of around 22.0°C sits comfortably within both species' preferred ranges.
Are Malaysian Trumpet Snail (MTS) or Paradise Fish aggressive?▾
Malaysian Trumpet Snail (MTS) is peaceful (0/10) and Paradise Fish is semi-aggressive (8/10). 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 Paradise Fish need?▾
Both species overlap in the 7–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Paradise Fish nip Malaysian Trumpet Snail (MTS)'s fins?▾
Paradise Fish is a known fin nipper. If Malaysian Trumpet Snail (MTS) has long or flowing fins, there is a real risk of fin damage. Keeping Paradise Fish in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Paradise Fish's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Paradise Fish 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.
