Can Apistogramma panduro and Flowerhorn Cichlid Live Together?
Apistogramma panduro and Flowerhorn Cichlid are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. 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 Apistogramma panduro and Flowerhorn Cichlid?
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
Apistogramma panduro is a moderately assertive species (6/10), while Flowerhorn Cichlid is highly aggressive (10/10). This notable difference means Flowerhorn Cichlid may occasionally assert dominance over Apistogramma panduro.
Apistogramma panduro and Flowerhorn Cichlid both frequent the Bottom (Substrate) and Middle (Open Water) 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. Two territorial species may clash over territory, especially in smaller tanks.
Water Parameters
The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.
The pH requirements of Apistogramma panduro (5–6.8) and Flowerhorn Cichlid (7.4–8) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Apistogramma panduro needs 1–5 dGH while Flowerhorn Cichlid requires 9–20 dGH.

Tank Setup
To house Apistogramma panduro 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Frequently Asked Questions
Can Apistogramma panduro and Flowerhorn Cichlid live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Apistogramma panduro and Flowerhorn Cichlid need?
A minimum of 280 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 Apistogramma panduro and Flowerhorn Cichlid together?
Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.
Are Apistogramma panduro or Flowerhorn Cichlid aggressive?
Apistogramma panduro is moderately assertive (6/10) and Flowerhorn Cichlid is highly aggressive (10/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Apistogramma panduro and Flowerhorn Cichlid need?
Their pH requirements do not overlap. Apistogramma panduro prefers 5–6.8, while Flowerhorn Cichlid needs 7.4–8. This makes them incompatible in the same water chemistry.
How do I manage Apistogramma panduro's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Apistogramma panduro 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.
