Can Afra Cichlid and Flash Pleco (L204) Live Together?
Afra Cichlid and Flash Pleco (L204) 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
Can your tank handle Afra Cichlid and Flash Pleco (L204)?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament
Afra Cichlid is a semi-aggressive species (8/10), while Flash Pleco (L204) is generally mild-mannered (4/10). This notable difference means Afra Cichlid may occasionally assert dominance over Flash Pleco (L204).
Afra Cichlid and Flash Pleco (L204) 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.
Worth noting: Flash Pleco (L204) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
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.
The pH requirements of Afra Cichlid (7.6–8.6) and Flash Pleco (L204) (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.
For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Afra Cichlid and Flash Pleco (L204) together, plan for an aquarium of at least 279 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), Established Algae (Otocinclus), 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.

Frequently Asked Questions
Can Afra Cichlid and Flash Pleco (L204) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Afra Cichlid and Flash Pleco (L204) need?
A minimum of 279 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 Afra Cichlid and Flash Pleco (L204) 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 Afra Cichlid or Flash Pleco (L204) aggressive?
Afra Cichlid is semi-aggressive (8/10) and Flash Pleco (L204) is generally mild-mannered (4/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Afra Cichlid and Flash Pleco (L204) need?
Their pH requirements do not overlap. Afra Cichlid prefers 7.6–8.6, while Flash Pleco (L204) needs 6–7.5. This makes them incompatible in the same water chemistry.
How do I manage Afra Cichlid's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Afra Cichlid 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.
Does Flash Pleco (L204) being nocturnal affect compatibility?
Flash Pleco (L204) is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Flash Pleco (L204) during evening hours.
