Behaviour & Temperament

Amano Shrimp is a peaceful species (1/10), while Gertrude's Spotted Blue-eye is peaceful (2/10). This modest difference means Gertrude's Spotted Blue-eye may occasionally assert dominance over Amano Shrimp.

Amano Shrimp and Gertrude's Spotted Blue-eye 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 21°C and 28°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 5–14 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Amano Shrimp and Gertrude's Spotted Blue-eye together, plan for an aquarium of at least 46 litres with a minimum length of 45 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 - Floating, Leaf Litter/Blackwater. 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.
