Can Malaysian Trumpet Snail (MTS) and Scat (Brackish) Live Together?

Malaysian Trumpet Snail (MTS) is a peaceful species (0/10), while Scat (Brackish) is generally mild-mannered (4/10). This notable difference means Scat (Brackish) may occasionally assert dominance over Malaysian Trumpet Snail (MTS).

Malaysian Trumpet Snail (MTS) and Scat (Brackish) 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.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

The safe temperature window for both species falls between 20°C and 28°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 12–25 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Malaysian Trumpet Snail (MTS) and Scat (Brackish) together, plan for an aquarium of at least 540 litres with a minimum length of 150 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while Scat (Brackish) requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich, while Scat (Brackish) requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Compromise where possible or prioritise the more critical need.

Malaysian Trumpet Snail (MTS) prefers Low (Still Water) flow while Scat (Brackish) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
