Can Cigar Shark (Mad Barb) and Malaysian Trumpet Snail (MTS) Live Together?

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

In terms of spatial distribution, Cigar Shark (Mad Barb) prefers the Middle (Open Water) and Top (Surface) zones, whereas Malaysian Trumpet Snail (MTS) occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Worth noting: Malaysian Trumpet Snail (MTS) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Cigar Shark (Mad Barb) is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°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 Cigar Shark (Mad Barb) and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 1000 litres with a minimum length of 240 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: Smooth Gravel (Sensitive Barbels), Sand (Sifters), Soil / Nutrient Rich. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Cigar Shark (Mad Barb) 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.

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

Cigar Shark (Mad Barb) 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.
