Behaviour & Temperament

Amano Shrimp is a peaceful species (1/10), while Turquoise Rainbowfish is peaceful (2/10). This modest difference means Turquoise Rainbowfish may occasionally assert dominance over Amano Shrimp.

Amano Shrimp and Turquoise 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.

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 20°C and 25°C. Aim for the midpoint of this range (around 22.5°C) for optimal comfort.

Both fish can tolerate a pH between 7 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 10–14 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Amano Shrimp and Turquoise Rainbowfish together, plan for an aquarium of at least 192 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: Established Algae (Otocinclus), Plants - Densely covered, Plants - lighly covered. Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
