Can Bamboo Shrimp and Least Killifish (Heterandria) Live Together?

Bamboo Shrimp is a peaceful species (0/10), while Least Killifish (Heterandria) is peaceful (1/10). This modest difference means Least Killifish (Heterandria) may occasionally assert dominance over Bamboo Shrimp.

Bamboo Shrimp and Least Killifish (Heterandria) both frequent the Middle (Open Water) and Bottom (Substrate) 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: Bamboo Shrimp is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 22°C and 27°C. Aim for the midpoint of this range (around 24.5°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 6–15 dGH. Regular testing will ensure conditions stay within this range.

To house Bamboo Shrimp and Least Killifish (Heterandria) together, plan for an aquarium of at least 90 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: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating. Meeting these requirements will help both species thrive.

Bamboo Shrimp prefers High (River/Stream) flow while Least Killifish (Heterandria) needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
