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

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

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

Bee Shrimp (Crystal Red / Black) and Pearly Ocellatus both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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 (Crystal Red / Black) (5.5–6.8) and Pearly Ocellatus (8–9) 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 Pearly Ocellatus requires 10–25 dGH.

To house Bee Shrimp (Crystal Red / Black) and Pearly Ocellatus together, plan for an aquarium of at least 38 litres with a minimum length of 45 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), Sand (Sifters), Shells (Breeding/Hiding). 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 Pearly Ocellatus requires Sand (Sifters). 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 (Crystal Red / Black) and Pearly Ocellatus 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.
