Can Deep Water Hap (Placidochromis electra) and Steindachner Dwarf Cichlid Live Together?

Deep Water Hap (Placidochromis electra) is a moderately assertive species (5/10), while Steindachner Dwarf Cichlid is generally mild-mannered (4/10). This modest difference means Deep Water Hap (Placidochromis electra) may occasionally assert dominance over Steindachner Dwarf Cichlid.

Deep Water Hap (Placidochromis electra) and Steindachner Dwarf Cichlid both frequent the Middle (Open Water) and 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Two territorial species may clash over territory, especially in smaller tanks.

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.

The pH requirements of Deep Water Hap (Placidochromis electra) (7.8–8.6) and Steindachner Dwarf Cichlid (5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

To house Deep Water Hap (Placidochromis electra) and Steindachner Dwarf Cichlid together, plan for an aquarium of at least 280 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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), Leaf Litter/Blackwater, Driftwood (Digestion/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.

Deep Water Hap (Placidochromis electra) and Steindachner Dwarf Cichlid are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
