Can Fosso Cichlid (Fossorochromis rostratus) and Tiger Shrimp Live Together?

Fosso Cichlid (Fossorochromis rostratus) is a moderately assertive species (6/10), while Tiger Shrimp is peaceful (0/10). This notable difference means Fosso Cichlid (Fossorochromis rostratus) may occasionally assert dominance over Tiger Shrimp.

Large aggression gap (6 points) between Fosso Cichlid (Fossorochromis rostratus) and Tiger Shrimp increases stress risk for the more peaceful fish.

Fosso Cichlid (Fossorochromis rostratus) and Tiger Shrimp both frequent the Bottom (Substrate) and Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Fosso Cichlid (Fossorochromis rostratus) (7.8–8.6) and Tiger Shrimp (6–7.4) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Fosso Cichlid (Fossorochromis rostratus) needs 10–25 dGH while Tiger Shrimp requires 4–8 dGH.

To house Fosso Cichlid (Fossorochromis rostratus) and Tiger Shrimp together, plan for an aquarium of at least 680 litres with a minimum length of 180 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.

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

Fosso Cichlid (Fossorochromis rostratus) 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.
