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

Half Banded Spiny Eel is a generally mild-mannered species (3/10), while Malaysian Trumpet Snail (MTS) is peaceful (0/10). This modest difference means Half Banded Spiny Eel may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

Half Banded Spiny Eel 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: Half Banded Spiny Eel is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Half Banded Spiny Eel is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°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 8–15 dGH. Regular testing will ensure conditions stay within this range.

To house Half Banded Spiny Eel and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 110 litres with a minimum length of 90 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), Smooth Gravel (Sensitive Barbels), Plants - Densely covered, Soil / Nutrient Rich. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Half Banded Spiny Eel requires Sand (Sifters), while Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich. These substrate types may be difficult to provide simultaneously. Half Banded Spiny Eel requires Smooth Gravel (Sensitive Barbels), 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 moderate (standard) 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. Half Banded Spiny Eel and Malaysian Trumpet Snail (MTS) 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. Half Banded Spiny Eel is a known shrimp eater and may prey on small invertebrates or nano fish like Malaysian Trumpet Snail (MTS).
