Can Rio Negro Dwarf Cichlid and Vampire Shrimp Live Together?

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

Large aggression gap (7 points) between Rio Negro Dwarf Cichlid and Vampire Shrimp increases stress risk for the more peaceful fish.

Rio Negro Dwarf Cichlid and Vampire 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: Aggressive fish may bully and stress shy, slow-moving species.

Worth noting: Vampire Shrimp is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Rio Negro Dwarf Cichlid needs 0–5 dGH while Vampire Shrimp requires 6–15 dGH.

To house Rio Negro Dwarf Cichlid and Vampire Shrimp together, plan for an aquarium of at least 110 litres with a minimum length of 80 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: Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Sand (Sifters). Meeting these requirements will help both species thrive.

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

Rio Negro Dwarf Cichlid and Vampire 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.
