Can Ajamaru Rainbowfish and Bee Shrimp Live Together?

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

In terms of spatial distribution, Ajamaru Rainbowfish prefers the Top (Surface) and Middle (Open Water) zones, whereas Bee Shrimp occupies the Bottom (Substrate) zone. 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: Ajamaru 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 Ajamaru Rainbowfish (7.2–8.5) and Bee Shrimp (5.5–6.8) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Ajamaru Rainbowfish and Bee Shrimp together, plan for an aquarium of at least 150 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: Plants - Densely covered, Soil / Nutrient Rich, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

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