Can your tank handle Deep Water Hap (Placidochromis electra) and Sturgeon Catfish?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Deep Water Hap (Placidochromis electra) is a moderately assertive species (5/10), while Sturgeon Catfish is moderately assertive (6/10). This modest difference means Sturgeon Catfish may occasionally assert dominance over Deep Water Hap (Placidochromis electra).

Deep Water Hap (Placidochromis electra) and Sturgeon Catfish both frequent the 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: Sturgeon Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

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 Sturgeon Catfish (6–7.5) 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.

Tank Setup

To house Deep Water Hap (Placidochromis electra) and Sturgeon Catfish together, plan for an aquarium of at least 800 litres with a minimum length of 180 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 Sturgeon Catfish 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 Sturgeon Catfish 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 Sturgeon Catfish need?

A minimum of 800 litres (tank length at least 180 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 Sturgeon Catfish 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 Sturgeon Catfish aggressive?

Deep Water Hap (Placidochromis electra) is moderately assertive (5/10) and Sturgeon Catfish is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Deep Water Hap (Placidochromis electra) and Sturgeon Catfish need?

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

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.

Does Sturgeon Catfish being nocturnal affect compatibility?

Sturgeon Catfish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Sturgeon Catfish during evening hours.
