Can Dwarf Green Pike Cichlid and Red Dwarf Rasbora Live Together?

Dwarf Green Pike Cichlid is a semi-aggressive species (7/10), while Red Dwarf Rasbora is peaceful (1/10). This notable difference means Dwarf Green Pike Cichlid may occasionally assert dominance over Red Dwarf Rasbora.

Large aggression gap (6 points) between Dwarf Green Pike Cichlid and Red Dwarf Rasbora increases stress risk for the more peaceful fish.

Dwarf Green Pike Cichlid and Red Dwarf Rasbora 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) 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 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

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 Red Dwarf Rasbora 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 - Densely covered. Meeting these requirements will help both species thrive.

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

Dwarf Green Pike Cichlid and Red Dwarf Rasbora 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 Red Dwarf Rasbora.
