Can Bee Shrimp (Crystal Red / Black) and Payara Live Together?

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

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

Bee Shrimp (Crystal Red / Black) and Payara both frequent the 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Payara 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 4–6 dGH. Regular testing will ensure conditions stay within this range.

To house Bee Shrimp (Crystal Red / Black) and Payara 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, Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

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

Bee Shrimp (Crystal Red / Black) prefers Low (Still Water) flow while Payara needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Bee Shrimp (Crystal Red / Black) and Payara 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.
