Can Andinoacara sp. Gold Saum and Flowerhorn Cichlid Live Together?

Andinoacara sp. Gold Saum is a semi-aggressive species (8/10), while Flowerhorn Cichlid is highly aggressive (10/10). This modest difference means Flowerhorn Cichlid may occasionally assert dominance over Andinoacara sp. Gold Saum.

Both Andinoacara sp. Gold Saum and Flowerhorn Cichlid are highly aggressive, increasing the risk of violent confrontations.

Andinoacara sp. Gold Saum and Flowerhorn Cichlid 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: Two territorial species may clash over territory, especially in smaller tanks. Two aggressive species housed together increases risk of fighting.

There is no temperature overlap between Andinoacara sp. Gold Saum (20–25°C) and Flowerhorn Cichlid (26–30°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.4 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 9–20 dGH. Regular testing will ensure conditions stay within this range.

To house Andinoacara sp. Gold Saum and Flowerhorn Cichlid together, plan for an aquarium of at least 280 litres with a minimum length of 120 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). Meeting these requirements will help both species thrive.

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

Andinoacara sp. Gold Saum and Flowerhorn Cichlid 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.
