Can Taiwan Reef Cichlid and Tiger Shrimp Live Together?

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

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

Taiwan Reef Cichlid 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: 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 Taiwan Reef Cichlid (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: Taiwan Reef Cichlid needs 10–20 dGH while Tiger Shrimp requires 4–8 dGH.

To house Taiwan Reef Cichlid and Tiger Shrimp together, plan for an aquarium of at least 280 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), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Taiwan Reef Cichlid 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.

Taiwan Reef Cichlid 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.
