At a Glance
Behaviour & Temperament
Bristlenose Pleco is a peaceful species (2/10), while Norman's Lampeye Killifish is peaceful (1/10). This modest difference means Bristlenose Pleco may occasionally assert dominance over Norman's Lampeye Killifish.
In terms of spatial distribution, Bristlenose Pleco prefers the Bottom (Substrate) zone, whereas Norman's Lampeye Killifish 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: Bristlenose Pleco is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Norman's Lampeye Killifish 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 27°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 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 4–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Bristlenose Pleco and Norman's Lampeye Killifish 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: Driftwood (Digestion/Hiding), Established Algae (Otocinclus), Plants - Densely covered, Plants - Floating. 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.
