At a Glance
Behaviour & Temperament
Assassin Snail is a peaceful species (2/10), while Zebra Danio is generally mild-mannered (3/10). This modest difference means Zebra Danio may occasionally assert dominance over Assassin Snail.
In terms of spatial distribution, Assassin Snail prefers the Bottom (Substrate) zone, whereas Zebra Danio occupies the Top (Surface) and Middle (Open Water) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
Worth noting: Zebra Danio is a known jumper, so a tight-fitting lid is essential.
Water Parameters
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.
Tank Setup
To house Assassin Snail and Zebra Danio together, plan for an aquarium of at least 46 litres with a minimum length of 60 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Assassin Snail prefers Low (Still Water) flow while Zebra Danio needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
