Behaviour & Temperament

Deep Water Hap (Placidochromis electra) is a moderately assertive species (5/10), while Sixbar Distichodus is semi-aggressive (7/10). This modest difference means Sixbar Distichodus may occasionally assert dominance over Deep Water Hap (Placidochromis electra).

Deep Water Hap (Placidochromis electra) and Sixbar Distichodus 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.

Worth noting: Sixbar Distichodus is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Deep Water Hap (Placidochromis electra) (7.8–8.6) and Sixbar Distichodus (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–20 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Deep Water Hap (Placidochromis electra) and Sixbar Distichodus together, plan for an aquarium of at least 1000 litres with a minimum length of 200 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), 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.

Why This Pairing Usually Fails in Practice

Deep Water Hap (Placidochromis electra) and Sixbar Distichodus 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.

Frequently Asked Questions

Can Deep Water Hap (Placidochromis electra) and Sixbar Distichodus live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Deep Water Hap (Placidochromis electra) and Sixbar Distichodus need?

A minimum of 1000 litres (tank length at least 200 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Deep Water Hap (Placidochromis electra) and Sixbar Distichodus together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Deep Water Hap (Placidochromis electra) or Sixbar Distichodus aggressive?

Deep Water Hap (Placidochromis electra) is moderately assertive (5/10) and Sixbar Distichodus is semi-aggressive (7/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Deep Water Hap (Placidochromis electra) and Sixbar Distichodus need?

Their pH requirements do not overlap. Deep Water Hap (Placidochromis electra) prefers 7.8–8.6, while Sixbar Distichodus needs 6–7.5. This makes them incompatible in the same water chemistry.

Will Sixbar Distichodus nip Deep Water Hap (Placidochromis electra)'s fins?

Sixbar Distichodus is a known fin nipper. If Deep Water Hap (Placidochromis electra) has long or flowing fins, there is a real risk of fin damage. Keeping Sixbar Distichodus in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Deep Water Hap (Placidochromis electra)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Deep Water Hap (Placidochromis electra) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
