Can Badis (Chameleon Fish) and Flowerhorn Cichlid Live Together?
Badis (Chameleon Fish) and Flowerhorn Cichlid are not recommended as tank mates due to no temperature overlap. 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 Badis (Chameleon Fish) 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
Badis (Chameleon Fish) is a moderately assertive species (5/10), while Flowerhorn Cichlid is highly aggressive (10/10). This notable difference means Flowerhorn Cichlid may occasionally assert dominance over Badis (Chameleon Fish).
Badis (Chameleon Fish) 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
There is no temperature overlap between Badis (Chameleon Fish) (15–25°C) and Flowerhorn Cichlid (26–30°C). This fundamental mismatch makes long-term cohabitation impractical.
Both fish can tolerate a pH between 7.4 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 9–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Badis (Chameleon Fish) 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), Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Flowerhorn Cichlid is a plant destroyer, which conflicts with Badis (Chameleon Fish)'s requirement for live plants. Compromise where possible or prioritise the more critical need.
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 Badis (Chameleon Fish) and Flowerhorn Cichlid live together?
No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.
What size tank do Badis (Chameleon Fish) 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 Badis (Chameleon Fish) and Flowerhorn Cichlid together?
Unfortunately, there is no temperature range that satisfies both species. Badis (Chameleon Fish) requires 15–25°C, while Flowerhorn Cichlid needs 26–30°C.
Are Badis (Chameleon Fish) or Flowerhorn Cichlid aggressive?
Badis (Chameleon Fish) is moderately assertive (5/10) 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 Badis (Chameleon Fish) and Flowerhorn Cichlid need?
Both species overlap in the 7.4–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
How do I manage Badis (Chameleon Fish)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Badis (Chameleon Fish) 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.
