At a Glance
Behaviour & Temperament
Amano Shrimp is a peaceful species (1/10), while Koi is peaceful (2/10). This modest difference means Koi may occasionally assert dominance over Amano Shrimp.
Amano Shrimp and Koi 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.
Worth noting: Amano Shrimp is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 18°C and 28°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.
Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 4–14 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Amano Shrimp and Koi together, plan for an aquarium of at least 4542 litres with a minimum length of 300 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, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Koi is a plant destroyer, which conflicts with Amano Shrimp's requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
