Can Cardinal Shrimp (Sulawesi) and Dwarf Green Pike Cichlid Live Together?

Cardinal Shrimp (Sulawesi) is a peaceful species (0/10), while Dwarf Green Pike Cichlid is semi-aggressive (7/10). This notable difference means Dwarf Green Pike Cichlid may occasionally assert dominance over Cardinal Shrimp (Sulawesi).

Large aggression gap (7 points) between Cardinal Shrimp (Sulawesi) and Dwarf Green Pike Cichlid increases stress risk for the more peaceful fish.

Cardinal Shrimp (Sulawesi) and Dwarf Green Pike 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

Worth noting: Dwarf Green Pike Cichlid is a known jumper, so a tight-fitting lid is essential.

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 Dwarf Green Pike Cichlid (5.5–7) 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.

To house Cardinal Shrimp (Sulawesi) and Dwarf Green Pike Cichlid together, plan for an aquarium of at least 130 litres with a minimum length of 90 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), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Cardinal Shrimp (Sulawesi) prefers Low (Still Water) flow while Dwarf Green Pike Cichlid needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Cardinal Shrimp (Sulawesi) and Dwarf Green Pike 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.

Feeding time deserves special attention with this pairing. Dwarf Green Pike Cichlid is a known shrimp eater and may prey on small invertebrates or nano fish like Cardinal Shrimp (Sulawesi).
