Can Malaysian Trumpet Snail (MTS) and Zebra Spiny Eel Live Together?

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

Malaysian Trumpet Snail (MTS) and Zebra Spiny Eel 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. Also, Zebra Spiny Eel is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°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 8–15 dGH. Regular testing will ensure conditions stay within this range.

To house Malaysian Trumpet Snail (MTS) and Zebra Spiny Eel together, plan for an aquarium of at least 110 litres with a minimum length of 80 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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, Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while Zebra Spiny Eel requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while Zebra Spiny Eel requires Smooth Gravel (Sensitive Barbels). 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Malaysian Trumpet Snail (MTS) and Zebra Spiny Eel need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

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