Can Dickfeld's Julie and Tiger Shrimp Live Together?

Dickfeld's Julie is a moderately assertive species (6/10), while Tiger Shrimp is peaceful (0/10). This notable difference means Dickfeld's Julie may occasionally assert dominance over Tiger Shrimp.

Large aggression gap (6 points) between Dickfeld's Julie and Tiger Shrimp increases stress risk for the more peaceful fish.

Dickfeld's Julie and Tiger Shrimp both frequent the Bottom (Substrate) and Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

The safe temperature window for both species falls between 23°C and 25°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

The pH requirements of Dickfeld's Julie (8–9) and Tiger Shrimp (6–7.4) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Dickfeld's Julie needs 10–25 dGH while Tiger Shrimp requires 4–8 dGH.

To house Dickfeld's Julie and Tiger Shrimp together, plan for an aquarium of at least 75 litres with a minimum length of 75 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), Established Algae (Otocinclus), Plants - Densely covered, Smooth Gravel (Sensitive Barbels). 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.

Dickfeld's Julie and Tiger 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.

Feeding time deserves special attention with this pairing. Dickfeld's Julie is a known shrimp eater and may prey on small invertebrates or nano fish like Tiger Shrimp.
