Can Dwarf Green Pike Cichlid and Kamaka Rainbowfish Live Together?

Dwarf Green Pike Cichlid is a semi-aggressive species (7/10), while Kamaka Rainbowfish is peaceful (2/10). This notable difference means Dwarf Green Pike Cichlid may occasionally assert dominance over Kamaka Rainbowfish.

Dwarf Green Pike Cichlid and Kamaka Rainbowfish both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Dwarf Green Pike Cichlid (5.5–7) and Kamaka Rainbowfish (7.4–8.4) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 8–10 dGH. Regular testing will ensure conditions stay within this range.

To house Dwarf Green Pike Cichlid and Kamaka Rainbowfish 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - lighly covered. Meeting these requirements will help both species thrive.

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

Dwarf Green Pike Cichlid and Kamaka Rainbowfish 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.
