Can Bee Shrimp (Crystal Red / Black) and Boeseman's Rainbowfish Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Boeseman's Rainbowfish is peaceful (2/10). This modest difference means Boeseman's Rainbowfish may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Boeseman's Rainbowfish 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Boeseman's Rainbowfish is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Bee Shrimp (Crystal Red / Black) (18–24°C) and Boeseman's Rainbowfish (26–30°C). This fundamental mismatch makes long-term cohabitation impractical.

The pH requirements of Bee Shrimp (Crystal Red / Black) (5.5–6.8) and Boeseman's Rainbowfish (7–8.1) 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 Boeseman's Rainbowfish requires 9–19 dGH.

To house Bee Shrimp (Crystal Red / Black) and Boeseman's Rainbowfish together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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), Plants - lighly 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.

Feeding time deserves special attention with this pairing. Boeseman's Rainbowfish is an aggressive eater that may prevent Bee Shrimp (Crystal Red / Black) from getting enough food.

Because Boeseman's Rainbowfish is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Bee Shrimp (Crystal Red / Black) receives an adequate share.
