Behaviour & Temperament

Afra Cichlid is a semi-aggressive species (8/10), while Leopoldi Stingray (Black Diamond) is moderately assertive (5/10). This modest difference means Afra Cichlid may occasionally assert dominance over Leopoldi Stingray (Black Diamond).

Afra Cichlid and Leopoldi Stingray (Black Diamond) 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.

Water Parameters

The safe temperature window for both species falls between 26Β°C and 28Β°C. Aim for the midpoint of this range (around 27.0Β°C) for optimal comfort.

The pH requirements of Afra Cichlid (7.6–8.6) and Leopoldi Stingray (Black Diamond) (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

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

Tank Setup

To house Afra Cichlid and Leopoldi Stingray (Black Diamond) together, plan for an aquarium of at least 1135 litres with a minimum length of 240 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), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). 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.

Frequently Asked Questions

Can Afra Cichlid and Leopoldi Stingray (Black Diamond) live together?

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

What size tank do Afra Cichlid and Leopoldi Stingray (Black Diamond) need?

A minimum of 1135 litres (tank length at least 240 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 Afra Cichlid and Leopoldi Stingray (Black Diamond) together?

Keep the aquarium between 26Β°C and 28Β°C. A target of around 27.0Β°C sits comfortably within both species' preferred ranges.

Are Afra Cichlid or Leopoldi Stingray (Black Diamond) aggressive?

Afra Cichlid is semi-aggressive (8/10) and Leopoldi Stingray (Black Diamond) is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Afra Cichlid and Leopoldi Stingray (Black Diamond) need?

Their pH requirements do not overlap. Afra Cichlid prefers 7.6–8.6, while Leopoldi Stingray (Black Diamond) needs 6–7.5. This makes them incompatible in the same water chemistry.

How do I manage Afra Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Afra Cichlid 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.
