Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Afra Cichlid and Red Hump Eartheater are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Afra Cichlid and Red Hump Eartheater?

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

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

Afra Cichlid and Red Hump Eartheater 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: Two territorial species may clash over territory, especially in smaller tanks.

Water Parameters

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 Afra Cichlid (7.6–8.6) and Red Hump Eartheater (6.5–7.5) 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 Afra Cichlid and Red Hump Eartheater together, plan for an aquarium of at least 353 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), Established Algae (Otocinclus). 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

Afra Cichlid and Red Hump Eartheater 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Afra Cichlid and Red Hump Eartheater.

Frequently Asked Questions

Can Afra Cichlid and Red Hump Eartheater live together?

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

What size tank do Afra Cichlid and Red Hump Eartheater need?

A minimum of 353 litres (tank length at least 120 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 Red Hump Eartheater together?

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

Are Afra Cichlid or Red Hump Eartheater aggressive?

Afra Cichlid is semi-aggressive (8/10) and Red Hump Eartheater is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Afra Cichlid and Red Hump Eartheater need?

Their pH requirements do not overlap. Afra Cichlid prefers 7.6–8.6, while Red Hump Eartheater needs 6.5–7.5. 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 décor that divides the tank into distinct zones works especially well.
