Can Haplochromis sp. 44 (Thick Skin) and Tiger Shrimp Live Together?

Haplochromis sp. 44 (Thick Skin) is a semi-aggressive species (8/10), while Tiger Shrimp is peaceful (0/10). This notable difference means Haplochromis sp. 44 (Thick Skin) may occasionally assert dominance over Tiger Shrimp.

Large aggression gap (8 points) between Haplochromis sp. 44 (Thick Skin) and Tiger Shrimp increases stress risk for the more peaceful fish.

Haplochromis sp. 44 (Thick Skin) and Tiger Shrimp 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

The safe temperature window for both species falls between 23°C and 25°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

The pH requirements of Haplochromis sp. 44 (Thick Skin) (7.5–8.6) and Tiger Shrimp (6–7.4) 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 Tiger Shrimp requires 4–8 dGH.

To house Haplochromis sp. 44 (Thick Skin) and Tiger Shrimp together, plan for an aquarium of at least 241 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), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Haplochromis sp. 44 (Thick Skin) is a plant destroyer, which conflicts with Tiger Shrimp's requirement for live plants. Compromise where possible or prioritise the more critical need.

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 Tiger Shrimp 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.
