Can Bee Shrimp (Crystal Red / Black) and Silver Tiger Perch (American Tigerfish) Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This notable difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Large aggression gap (7 points) between Bee Shrimp (Crystal Red / Black) and Silver Tiger Perch (American Tigerfish) increases stress risk for the more peaceful fish.

Bee Shrimp (Crystal Red / Black) and Silver Tiger Perch (American Tigerfish) 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 Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species.

The safe temperature window for both species falls between 20°C and 24°C. Aim for the midpoint of this range (around 22.0°C) for optimal comfort.

The pH requirements of Bee Shrimp (Crystal Red / Black) (5.5–6.8) and Silver Tiger Perch (American Tigerfish) (7.5–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Bee Shrimp (Crystal Red / Black) needs 3–6 dGH while Silver Tiger Perch (American Tigerfish) requires 15–30 dGH.

To house Bee Shrimp (Crystal Red / Black) and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 650 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: Soil / Nutrient Rich, Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

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

Bee Shrimp (Crystal Red / Black) and Silver Tiger Perch (American Tigerfish) 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.
