Can Bearded Cory and Black Belt Cichlid Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 1, 2026
Not Recommended

Bearded Cory and Black Belt 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.

Can your tank handle Bearded Cory and Black Belt 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

Bearded Cory is a peaceful species (2/10), while Black Belt Cichlid is semi-aggressive (8/10). This notable difference means Black Belt Cichlid may occasionally assert dominance over Bearded Cory.

Large aggression gap (6 points) between Bearded Cory and Black Belt Cichlid increases stress risk for the more peaceful fish.

Bearded Cory and Black Belt Cichlid 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

There is no temperature overlap between Bearded Cory (16–23°C) and Black Belt Cichlid (24–29°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7 and 7.4. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 8–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bearded Cory and Black Belt Cichlid together, plan for an aquarium of at least 450 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), Driftwood (Digestion/Hiding). 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

Bearded Cory and Black Belt Cichlid 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 Bearded Cory and Black Belt Cichlid.

Frequently Asked Questions

Can Bearded Cory and Black Belt Cichlid live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Bearded Cory and Black Belt Cichlid need?

A minimum of 450 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 Bearded Cory and Black Belt Cichlid together?

Unfortunately, there is no temperature range that satisfies both species. Bearded Cory requires 16–23°C, while Black Belt Cichlid needs 24–29°C.

Are Bearded Cory or Black Belt Cichlid aggressive?

Bearded Cory is peaceful (2/10) and Black Belt Cichlid 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 Bearded Cory and Black Belt Cichlid need?

Both species overlap in the 7–7.4 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Black Belt Cichlid's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Black Belt 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.
