Behaviour & Temperament

Amano Shrimp is a peaceful species (1/10), while Wrestling Halfbeak is generally mild-mannered (4/10). This modest difference means Wrestling Halfbeak may occasionally assert dominance over Amano Shrimp.

In terms of spatial distribution, Amano Shrimp prefers the Bottom (Substrate) and Middle (Open Water) zones, whereas Wrestling Halfbeak occupies the Top (Surface) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°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 Wrestling Halfbeak together, plan for an aquarium of at least 66 litres with a minimum length of 60 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. 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.
