Can Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) Live Together?
Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Demasoni Cichlid (Mbuna) is a highly aggressive species (9/10), while Gold Nugget Pleco (L018) is moderately assertive (6/10). This modest difference means Demasoni Cichlid (Mbuna) may occasionally assert dominance over Gold Nugget Pleco (L018).
Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) both frequent the 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: Aggressive fish may bully and stress shy, slow-moving species. Hyperactive swimmers can stress shy, slow-moving species through constant motion. Two territorial species may clash over territory, especially in smaller tanks.
Water Parameters
The safe temperature window for both species falls between 27°C and 28°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.
The pH requirements of Demasoni Cichlid (Mbuna) (7.6–8.6) and Gold Nugget Pleco (L018) (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) together, plan for an aquarium of at least 300 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.
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), Established Algae (Otocinclus), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). 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.

Frequently Asked Questions
Can Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) live together?▾
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) need?▾
A minimum of 300 litres (tank length at least 120 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.
What water temperature is best for Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) together?▾
Keep the aquarium between 27°C and 28°C. A target of around 27.5°C sits comfortably within both species' preferred ranges.
Are Demasoni Cichlid (Mbuna) or Gold Nugget Pleco (L018) aggressive?▾
Demasoni Cichlid (Mbuna) is highly aggressive (9/10) and Gold Nugget Pleco (L018) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Demasoni Cichlid (Mbuna) and Gold Nugget Pleco (L018) need?▾
Their pH requirements do not overlap. Demasoni Cichlid (Mbuna) prefers 7.6–8.6, while Gold Nugget Pleco (L018) needs 6–7.5. This makes them incompatible in the same water chemistry.
How do I manage Demasoni Cichlid (Mbuna)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Demasoni Cichlid (Mbuna) 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.
