Can Norman's Lampeye Killifish and Shell Dweller (Multi) Live Together?

Norman's Lampeye Killifish is a peaceful species (1/10), while Shell Dweller (Multi) is moderately assertive (6/10). This notable difference means Shell Dweller (Multi) may occasionally assert dominance over Norman's Lampeye Killifish.

In terms of spatial distribution, Norman's Lampeye Killifish prefers the Top (Surface) and Middle (Open Water) zones, whereas Shell Dweller (Multi) 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: Norman's Lampeye Killifish is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Norman's Lampeye Killifish (6.5–7.5) and Shell Dweller (Multi) (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Norman's Lampeye Killifish and Shell Dweller (Multi) together, plan for an aquarium of at least 46 litres with a minimum length of 45 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 - Densely covered, Plants - Floating, Sand (Sifters), Shells (Breeding/Hiding). 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.
