At a Glance
Behaviour & Temperament
Clown Killifish is a peaceful species (2/10), while Zebra Pleco (L046) is generally mild-mannered (3/10). This modest difference means Zebra Pleco (L046) may occasionally assert dominance over Clown Killifish.
In terms of spatial distribution, Clown Killifish prefers the Top (Surface) zone, whereas Zebra Pleco (L046) 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.
Worth noting: Zebra Pleco (L046) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Clown Killifish is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 27°C and 27°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.
Both fish can tolerate a pH between 6 and 7. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 2–8 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Clown Killifish and Zebra Pleco (L046) together, plan for an aquarium of at least 90 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: Plants - Floating, Plants - Densely covered, Leaf Litter/Blackwater, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Clown Killifish prefers Low (Still Water) flow while Zebra Pleco (L046) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
