Can Malaysian Trumpet Snail (MTS) and Silver Hatchetfish Live Together?

Malaysian Trumpet Snail (MTS) is a peaceful species (0/10), while Silver Hatchetfish is peaceful (1/10). This modest difference means Silver Hatchetfish may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

In terms of spatial distribution, Malaysian Trumpet Snail (MTS) prefers the Bottom (Substrate) zone, whereas Silver Hatchetfish occupies the Top (Surface) 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. Also, Silver Hatchetfish is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°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 Malaysian Trumpet Snail (MTS) and Silver Hatchetfish together, plan for an aquarium of at least 75 litres with a minimum length of 60 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, 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.
