At a Glance
Behaviour & Temperament
Cherry Shrimp is a peaceful species (0/10), while Rosy Barb is generally mild-mannered (3/10). This modest difference means Rosy Barb may occasionally assert dominance over Cherry Shrimp.
Cherry Shrimp and Rosy Barb 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.
Water Parameters
The safe temperature window for both species falls between 18°C and 25°C. Aim for the midpoint of this range (around 21.5°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 6–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Cherry Shrimp and Rosy Barb together, plan for an aquarium of at least 132 litres with a minimum length of 80 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: Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Rosy Barb is a plant destroyer, which conflicts with Cherry Shrimp'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.
