Can Asher Cory and Fairy Cichlid (Brichardi) Live Together?
Asher Cory and Fairy Cichlid (Brichardi) 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 Asher Cory and Fairy Cichlid (Brichardi)?
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
Asher Cory is a peaceful species (1/10), while Fairy Cichlid (Brichardi) is semi-aggressive (8/10). This notable difference means Fairy Cichlid (Brichardi) may occasionally assert dominance over Asher Cory.
Large aggression gap (7 points) between Asher Cory and Fairy Cichlid (Brichardi) increases stress risk for the more peaceful fish.
Asher Cory and Fairy Cichlid (Brichardi) 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.
Water Parameters
The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.
The pH requirements of Asher Cory (5–7.5) and Fairy Cichlid (Brichardi) (8–9) 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 Asher Cory and Fairy Cichlid (Brichardi) together, plan for an aquarium of at least 110 litres with a minimum length of 75 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, 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 Asher Cory and Fairy Cichlid (Brichardi) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Asher Cory and Fairy Cichlid (Brichardi) need?
A minimum of 110 litres (tank length at least 75 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 Asher Cory and Fairy Cichlid (Brichardi) together?
Keep the aquarium between 23°C and 27°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.
Are Asher Cory or Fairy Cichlid (Brichardi) aggressive?
Asher Cory is peaceful (1/10) and Fairy Cichlid (Brichardi) is semi-aggressive (8/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Asher Cory and Fairy Cichlid (Brichardi) need?
Their pH requirements do not overlap. Asher Cory prefers 5–7.5, while Fairy Cichlid (Brichardi) needs 8–9. This makes them incompatible in the same water chemistry.
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.
