Can Pike Cichlid (Xingu) and Tequila Splitfin Live Together?

Pike Cichlid (Xingu) is a highly aggressive species (9/10), while Tequila Splitfin is moderately assertive (5/10). This notable difference means Pike Cichlid (Xingu) may occasionally assert dominance over Tequila Splitfin.

Pike Cichlid (Xingu) and Tequila Splitfin 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.

Worth noting: Pike Cichlid (Xingu) is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Pike Cichlid (Xingu) (26–30°C) and Tequila Splitfin (20–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 6–12 dGH. Regular testing will ensure conditions stay within this range.

To house Pike Cichlid (Xingu) and Tequila Splitfin together, plan for an aquarium of at least 560 litres with a minimum length of 180 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), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Plants - Densely 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.

Pike Cichlid (Xingu) and Tequila Splitfin 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.
