Can Orange Delight Shrimp and Redline Rasbora Live Together?

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

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

Worth noting: Redline Rasbora is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 26°C and 27°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

The pH requirements of Orange Delight Shrimp (7.5–8.5) and Redline Rasbora (4–6.8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 4–8 dGH. Regular testing will ensure conditions stay within this range.

To house Orange Delight Shrimp and Redline Rasbora together, plan for an aquarium of at least 80 litres with a minimum length of 80 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating. 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.

Orange Delight Shrimp and Redline Rasbora are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
