Can Parrot Cichlid and White Saum (Green Terror) Live Together?

Parrot Cichlid is a semi-aggressive species (7/10), while White Saum (Green Terror) is semi-aggressive (8/10). This modest difference means White Saum (Green Terror) may occasionally assert dominance over Parrot Cichlid.

Both Parrot Cichlid and White Saum (Green Terror) are highly aggressive, increasing the risk of violent confrontations.

Parrot Cichlid and White Saum (Green Terror) 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 Parrot Cichlid (26–30°C) and White Saum (Green Terror) (20–25°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 and 7.2. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–8 dGH. Regular testing will ensure conditions stay within this range.

To house Parrot Cichlid and White Saum (Green Terror) together, plan for an aquarium of at least 450 litres with a minimum length of 150 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: Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Sand (Sifters), 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.

Parrot Cichlid and White Saum (Green Terror) 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.
