Can Dwarf Rasbora and Purple Zebra Shrimp Live Together?

Dwarf Rasbora is a peaceful species (1/10), while Purple Zebra Shrimp is peaceful (0/10). This modest difference means Dwarf Rasbora may occasionally assert dominance over Purple Zebra Shrimp.

In terms of spatial distribution, Dwarf Rasbora prefers the Middle (Open Water) zone, whereas Purple Zebra Shrimp occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–10 dGH. Regular testing will ensure conditions stay within this range.

To house Dwarf Rasbora and Purple Zebra Shrimp together, plan for an aquarium of at least 19 litres with a minimum length of 30 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

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