Can Fairy Cichlid (Brichardi) and Finger Fish Live Together?
Fairy Cichlid (Brichardi) and Finger Fish are not recommended as tank mates due to incompatible water types. 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 Fairy Cichlid (Brichardi) and Finger Fish?
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
Fairy Cichlid (Brichardi) is a semi-aggressive species (8/10), while Finger Fish is moderately assertive (5/10). This modest difference means Fairy Cichlid (Brichardi) may occasionally assert dominance over Finger Fish.
Fairy Cichlid (Brichardi) and Finger Fish both frequent the 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.
Water Parameters
The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.
Both fish can tolerate a pH between 8 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 12–25 dGH. Regular testing will ensure conditions stay within this range.
Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.
Tank Setup
To house Fairy Cichlid (Brichardi) and Finger Fish together, plan for an aquarium of at least 470 litres with a minimum length of 150 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), 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.
Why This Pairing Usually Fails in Practice
Fairy Cichlid (Brichardi) and Finger Fish are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Fairy Cichlid (Brichardi) and Finger Fish.
Frequently Asked Questions
Can Fairy Cichlid (Brichardi) and Finger Fish live together?
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do Fairy Cichlid (Brichardi) and Finger Fish need?
A minimum of 470 litres (tank length at least 150 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 Fairy Cichlid (Brichardi) and Finger Fish together?
Keep the aquarium between 24°C and 27°C. A target of around 25.5°C sits comfortably within both species' preferred ranges.
Are Fairy Cichlid (Brichardi) or Finger Fish aggressive?
Fairy Cichlid (Brichardi) is semi-aggressive (8/10) and Finger Fish is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Fairy Cichlid (Brichardi) and Finger Fish need?
Both species overlap in the 8–8.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Finger Fish nip Fairy Cichlid (Brichardi)'s fins?
Finger Fish is a known fin nipper. If Fairy Cichlid (Brichardi) has long or flowing fins, there is a real risk of fin damage. Keeping Finger Fish in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Fairy Cichlid (Brichardi)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Fairy Cichlid (Brichardi) 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.
