Can Bee Shrimp and Silver Arowana Live Together?

Bee Shrimp is a peaceful species (0/10), while Silver Arowana is moderately assertive (6/10). This notable difference means Silver Arowana may occasionally assert dominance over Bee Shrimp.

Large aggression gap (6 points) between Bee Shrimp and Silver Arowana increases stress risk for the more peaceful fish.

In terms of spatial distribution, Bee Shrimp prefers the Bottom (Substrate) zone, whereas Silver Arowana occupies the Top (Surface) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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. Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Silver Arowana is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 24°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 6.8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 3–6 dGH. Regular testing will ensure conditions stay within this range.

To house Bee Shrimp and Silver Arowana together, plan for an aquarium of at least 1000 litres with a minimum length of 240 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, Leaf Litter/Blackwater, Plants - Densely covered, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Bee Shrimp requires Soil / Nutrient Rich, while Silver Arowana requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Compromise where possible or prioritise the more critical need.

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

Bee Shrimp and Silver Arowana 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.
