Reviewed by Guidarium Editorial DeskUpdated May 3, 2026
Not Recommended

Bearded Cory and Buettikoferi Bichir 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 Buettikoferi Bichir?

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 Buettikoferi Bichir is moderately assertive (6/10). This notable difference means Buettikoferi Bichir may occasionally assert dominance over Bearded Cory.

Bearded Cory and Buettikoferi Bichir 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.

Worth noting: Buettikoferi Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Buettikoferi Bichir is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Bearded Cory (16–23°C) and Buettikoferi Bichir (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 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 5–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bearded Cory and Buettikoferi Bichir together, plan for an aquarium of at least 200 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), Smooth Gravel (Sensitive Barbels), 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 Buettikoferi Bichir 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.

Frequently Asked Questions

Can Bearded Cory and Buettikoferi Bichir 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 Buettikoferi Bichir need?

A minimum of 200 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 Bearded Cory and Buettikoferi Bichir together?

Unfortunately, there is no temperature range that satisfies both species. Bearded Cory requires 16–23°C, while Buettikoferi Bichir needs 24–28°C.

Are Bearded Cory or Buettikoferi Bichir aggressive?

Bearded Cory is peaceful (2/10) and Buettikoferi Bichir is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Bearded Cory and Buettikoferi Bichir need?

Both species overlap in the 6.5–7.4 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Buettikoferi Bichir being nocturnal affect compatibility?

Buettikoferi Bichir is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Buettikoferi Bichir during evening hours.
