Can Duboisi Cichlid (Tropheus) and Green Terror Live Together?
Keeping Duboisi Cichlid (Tropheus) and Green Terror together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 336 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Both Duboisi Cichlid (Tropheus) and Green Terror are semi-aggressive species with an aggression score of 8/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.
Both Duboisi Cichlid (Tropheus) and Green Terror are highly aggressive, increasing the risk of violent confrontations.
Duboisi Cichlid (Tropheus) and 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.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Duboisi Cichlid (Tropheus) and Green Terror to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.
Water Parameters
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.
Both fish can tolerate a pH between 8 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 10–20 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Duboisi Cichlid (Tropheus) and Green Terror together, plan for an aquarium of at least 336 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Sand (Sifters), Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). 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.
Frequently Asked Questions
Can Duboisi Cichlid (Tropheus) and Green Terror live together?▾

What water temperature is best for Duboisi Cichlid (Tropheus) and Green Terror together?▾
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Duboisi Cichlid (Tropheus) or Green Terror aggressive?▾
Duboisi Cichlid (Tropheus) is semi-aggressive (8/10) and Green Terror is semi-aggressive (8/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Duboisi Cichlid (Tropheus) and Green Terror need?▾
Both species overlap in the 8–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Duboisi Cichlid (Tropheus)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Duboisi Cichlid (Tropheus) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
