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

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Pearl Eartheater is moderately assertive (6/10). This notable difference means Pearl Eartheater may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Large aggression gap (6 points) between Bee Shrimp (Crystal Red / Black) and Pearl Eartheater increases stress risk for the more peaceful fish.

Bee Shrimp (Crystal Red / Black) and Pearl Eartheater both frequent the Bottom (Substrate) and 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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Bee Shrimp (Crystal Red / Black) and Pearl Eartheater to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

The safe temperature window for both species falls between 20°C and 24°C. Aim for the midpoint of this range (around 22.0°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 5–6 dGH. Regular testing will ensure conditions stay within this range.

To house Bee Shrimp (Crystal Red / Black) and Pearl Eartheater together, plan for an aquarium of at least 250 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Soil / Nutrient Rich, Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Established Algae (Otocinclus), Sand (Sifters), 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 Pearl Eartheater requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich, while Pearl Eartheater requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Pearl Eartheater is a plant destroyer, which conflicts with Bee Shrimp (Crystal Red / Black)'s requirement for live plants. 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Bee Shrimp (Crystal Red / Black) and Pearl Eartheater need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
