Can Neolamprologus Similis and Orange Delight Shrimp Live Together?

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

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

Neolamprologus Similis and Orange Delight Shrimp 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.

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.

Both fish can tolerate a pH between 7.8 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

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

To house Neolamprologus Similis and Orange Delight Shrimp together, plan for an aquarium of at least 38 litres with a minimum length of 45 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), Shells (Breeding/Hiding), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

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

Neolamprologus Similis and Orange Delight Shrimp 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.
