Can Apistogramma uaupesi and Malaysian Trumpet Snail (MTS) Live Together?

Apistogramma uaupesi is a moderately assertive species (5/10), while Malaysian Trumpet Snail (MTS) is peaceful (0/10). This notable difference means Apistogramma uaupesi may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

Apistogramma uaupesi 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.

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

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 24°C and 29°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

The pH requirements of Apistogramma uaupesi (4–6) and Malaysian Trumpet Snail (MTS) (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Apistogramma uaupesi needs 0–5 dGH while Malaysian Trumpet Snail (MTS) requires 8–25 dGH.

To house Apistogramma uaupesi and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 60 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Soil / Nutrient Rich. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Apistogramma uaupesi requires Sand (Sifters), while Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich. 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.

Apistogramma uaupesi 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.

Feeding time deserves special attention with this pairing. Apistogramma uaupesi is a known shrimp eater and may prey on small invertebrates or nano fish like Malaysian Trumpet Snail (MTS).
