Can Bee Shrimp and Mubi Rainbowfish Live Together?

Bee Shrimp is a peaceful species (0/10), while Mubi Rainbowfish is peaceful (2/10). This modest difference means Mubi Rainbowfish may occasionally assert dominance over Bee Shrimp.

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

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

Worth noting: Mubi Rainbowfish 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.

The pH requirements of Bee Shrimp (5.5–6.8) and Mubi Rainbowfish (7–8.2) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Bee Shrimp needs 3–6 dGH while Mubi Rainbowfish requires 8–20 dGH.

To house Bee Shrimp and Mubi Rainbowfish together, plan for an aquarium of at least 110 litres with a minimum length of 90 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. 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 and Mubi Rainbowfish 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.
