Can Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid Live Together?
Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid 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 Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid?
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
Cardinal Shrimp (Sulawesi) is a peaceful species (0/10), while Three-striped Dwarf Cichlid is generally mild-mannered (4/10). This notable difference means Three-striped Dwarf Cichlid may occasionally assert dominance over Cardinal Shrimp (Sulawesi).
Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid 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.
Water Parameters
The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.
The pH requirements of Cardinal Shrimp (Sulawesi) (7.5–8.5) and Three-striped Dwarf Cichlid (5–7) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 4–8 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid together, plan for an aquarium of at least 60 litres with a minimum length of 60 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: Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), 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.
Why This Pairing Usually Fails in Practice
Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid 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.

Frequently Asked Questions
Can Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid need?
A minimum of 60 litres (tank length at least 60 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 Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid together?
Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.
Are Cardinal Shrimp (Sulawesi) or Three-striped Dwarf Cichlid aggressive?
Cardinal Shrimp (Sulawesi) is peaceful (0/10) and Three-striped Dwarf Cichlid is generally mild-mannered (4/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Cardinal Shrimp (Sulawesi) and Three-striped Dwarf Cichlid need?
Their pH requirements do not overlap. Cardinal Shrimp (Sulawesi) prefers 7.5–8.5, while Three-striped Dwarf Cichlid needs 5–7. This makes them incompatible in the same water chemistry.
How do I manage Three-striped Dwarf Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Three-striped Dwarf Cichlid 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.
