Can Nyererei Victorian Cichlid and Rummy-Nose Tetra Live Together?

Nyererei Victorian Cichlid is a semi-aggressive species (7/10), while Rummy-Nose Tetra is peaceful (1/10). This notable difference means Nyererei Victorian Cichlid may occasionally assert dominance over Rummy-Nose Tetra.

Large aggression gap (6 points) between Nyererei Victorian Cichlid and Rummy-Nose Tetra increases stress risk for the more peaceful fish.

Nyererei Victorian Cichlid and Rummy-Nose Tetra both frequent the Middle (Open Water) and 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. Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Nyererei Victorian Cichlid (7.4–8.6) and Rummy-Nose Tetra (5.5–7) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 8–12 dGH. Regular testing will ensure conditions stay within this range.

To house Nyererei Victorian Cichlid and Rummy-Nose Tetra together, plan for an aquarium of at least 258 litres with a minimum length of 100 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), Plants - Densely covered, Plants - lighly covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Nyererei Victorian Cichlid is a plant destroyer, which conflicts with Rummy-Nose Tetra's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Nyererei Victorian Cichlid and Rummy-Nose Tetra 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. Nyererei Victorian Cichlid is a known shrimp eater and may prey on small invertebrates or nano fish like Rummy-Nose Tetra.
