Can Haplochromis sp. 44 (Thick Skin) and Parrot Cichlid Live Together?

Haplochromis sp. 44 (Thick Skin) is a semi-aggressive species (8/10), while Parrot Cichlid is semi-aggressive (7/10). This modest difference means Haplochromis sp. 44 (Thick Skin) may occasionally assert dominance over Parrot Cichlid.

Both Haplochromis sp. 44 (Thick Skin) and Parrot Cichlid are highly aggressive, increasing the risk of violent confrontations.

Haplochromis sp. 44 (Thick Skin) and Parrot Cichlid 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. Two aggressive species housed together increases risk of fighting.

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

The pH requirements of Haplochromis sp. 44 (Thick Skin) (7.5–8.6) and Parrot Cichlid (5.5–7.2) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Haplochromis sp. 44 (Thick Skin) needs 10–20 dGH while Parrot Cichlid requires 1–8 dGH.

To house Haplochromis sp. 44 (Thick Skin) and Parrot Cichlid together, plan for an aquarium of at least 450 litres with a minimum length of 150 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater. 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.

Haplochromis sp. 44 (Thick Skin) and Parrot Cichlid 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.
