Behaviour & Temperament

Adonis Pleco is a semi-aggressive species (8/10), while Deep Water Hap (Placidochromis electra) is moderately assertive (5/10). This modest difference means Adonis Pleco may occasionally assert dominance over Deep Water Hap (Placidochromis electra).

Adonis Pleco and Deep Water Hap (Placidochromis electra) 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

Worth noting: Adonis Pleco 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 24Β°C and 28Β°C. Aim for the midpoint of this range (around 26.0Β°C) for optimal comfort.

The pH requirements of Adonis Pleco (6–7.5) and Deep Water Hap (Placidochromis electra) (7.8–8.6) 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 Adonis Pleco and Deep Water Hap (Placidochromis electra) together, plan for an aquarium of at least 1500 litres with a minimum length of 300 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: Driftwood (Digestion/Hiding), Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions

Can Adonis Pleco and Deep Water Hap (Placidochromis electra) live together?

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

What size tank do Adonis Pleco and Deep Water Hap (Placidochromis electra) need?

A minimum of 1500 litres (tank length at least 300 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 Adonis Pleco and Deep Water Hap (Placidochromis electra) together?

Keep the aquarium between 24Β°C and 28Β°C. A target of around 26.0Β°C sits comfortably within both species' preferred ranges.

Are Adonis Pleco or Deep Water Hap (Placidochromis electra) aggressive?

Adonis Pleco is semi-aggressive (8/10) and Deep Water Hap (Placidochromis electra) is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Adonis Pleco and Deep Water Hap (Placidochromis electra) need?

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

How do I manage Adonis Pleco's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Adonis Pleco space to claim a territory without encroaching on the other fish's area. Adding dΓ©cor that divides the tank into distinct zones works especially well.

Does Adonis Pleco being nocturnal affect compatibility?

Adonis Pleco 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 Adonis Pleco during evening hours.
