Can Indonesian Datnoid (Tiger Fish) and Malaysian Trumpet Snail (MTS) Live Together?
Indonesian Datnoid (Tiger Fish) and Malaysian Trumpet Snail (MTS) are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Indonesian Datnoid (Tiger Fish) is a moderately assertive species (6/10), while Malaysian Trumpet Snail (MTS) is peaceful (0/10). This notable difference means Indonesian Datnoid (Tiger Fish) may occasionally assert dominance over Malaysian Trumpet Snail (MTS).
Large aggression gap (6 points) between Indonesian Datnoid (Tiger Fish) and Malaysian Trumpet Snail (MTS) increases stress risk for the more peaceful fish.
Indonesian Datnoid (Tiger Fish) 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.
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..
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.
Water Parameters
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. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Indonesian Datnoid (Tiger Fish) and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 816 litres with a minimum length of 180 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Driftwood (Digestion/Hiding), Plants - Densely covered, Sand (Sifters), Soil / Nutrient Rich. Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Are Indonesian Datnoid (Tiger Fish) or Malaysian Trumpet Snail (MTS) aggressive?▾
Indonesian Datnoid (Tiger Fish) is moderately assertive (6/10) and Malaysian Trumpet Snail (MTS) is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Indonesian Datnoid (Tiger Fish) and Malaysian Trumpet Snail (MTS) need?▾
Both species overlap in the 7–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Does Malaysian Trumpet Snail (MTS) being nocturnal affect compatibility?▾
