Can Dickfeld's Julie and Purple Zebra Shrimp Live Together?
Dickfeld's Julie and Purple Zebra Shrimp are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Can your tank handle Dickfeld's Julie and Purple Zebra Shrimp?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.
Behaviour & Temperament
Dickfeld's Julie is a moderately assertive species (6/10), while Purple Zebra Shrimp is peaceful (0/10). This notable difference means Dickfeld's Julie may occasionally assert dominance over Purple Zebra Shrimp.
Large aggression gap (6 points) between Dickfeld's Julie and Purple Zebra Shrimp increases stress risk for the more peaceful fish.
Dickfeld's Julie and Purple Zebra 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.
Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.
Water Parameters
The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.
The pH requirements of Dickfeld's Julie (8–9) and Purple Zebra Shrimp (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Dickfeld's Julie and Purple Zebra 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), Leaf Litter/Blackwater, Plants - Densely covered. 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.
Why This Pairing Usually Fails in Practice
Dickfeld's Julie and Purple Zebra 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 Purple Zebra Shrimp.
Frequently Asked Questions
Can Dickfeld's Julie and Purple Zebra Shrimp live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Dickfeld's Julie and Purple Zebra Shrimp need?
A minimum of 75 litres (tank length at least 75 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Dickfeld's Julie and Purple Zebra Shrimp together?
Keep the aquarium between 23°C and 27°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.
Are Dickfeld's Julie or Purple Zebra Shrimp aggressive?
Dickfeld's Julie is moderately assertive (6/10) and Purple Zebra Shrimp is peaceful (0/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Dickfeld's Julie and Purple Zebra Shrimp need?
Their pH requirements do not overlap. Dickfeld's Julie prefers 8–9, while Purple Zebra Shrimp needs 6–7.5. This makes them incompatible in the same water chemistry.
How do I manage Dickfeld's Julie's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Dickfeld's Julie space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
