Can Orange Delight Shrimp and Redtail Splitfin Live Together?

Orange Delight Shrimp is a peaceful species (0/10), while Redtail Splitfin is moderately assertive (6/10). This notable difference means Redtail Splitfin may occasionally assert dominance over Orange Delight Shrimp.

Large aggression gap (6 points) between Orange Delight Shrimp and Redtail Splitfin increases stress risk for the more peaceful fish.

In terms of spatial distribution, Orange Delight Shrimp prefers the Bottom (Substrate) zone, whereas Redtail Splitfin 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.

The safe temperature window for both species falls between 26°C and 26°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Orange Delight Shrimp needs 4–8 dGH while Redtail Splitfin requires 10–25 dGH.

To house Orange Delight Shrimp and Redtail Splitfin together, plan for an aquarium of at least 110 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), Plants - Densely covered. 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 Redtail Splitfin 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.
