Can Licorice Gourami and Malaysian Trumpet Snail (MTS) Live Together?

Licorice Gourami is a peaceful species (2/10), while Malaysian Trumpet Snail (MTS) is peaceful (0/10). This modest difference means Licorice Gourami may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

Licorice Gourami 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 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Licorice Gourami (3–6) and Malaysian Trumpet Snail (MTS) (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Licorice Gourami needs 0–4 dGH while Malaysian Trumpet Snail (MTS) requires 8–25 dGH.

To house Licorice Gourami and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 19 litres with a minimum length of 30 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding), 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.

Licorice Gourami and Malaysian Trumpet Snail (MTS) 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.
