Can Orange Delight Shrimp and Prionotos Cory (Scleromystax) Live Together?

Orange Delight Shrimp is a peaceful species (0/10), while Prionotos Cory (Scleromystax) is peaceful (2/10). This modest difference means Prionotos Cory (Scleromystax) may occasionally assert dominance over Orange Delight Shrimp.

Orange Delight Shrimp and Prionotos Cory (Scleromystax) both frequent the 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.

There is no temperature overlap between Orange Delight Shrimp (26–29°C) and Prionotos Cory (Scleromystax) (18–25°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

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 Prionotos Cory (Scleromystax) together, plan for an aquarium of at least 90 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. 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 Prionotos Cory (Scleromystax) 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.
