Can Bearded Cory and New Guinea Tigerfish Live Together?
Bearded Cory and New Guinea Tigerfish 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 Bearded Cory and New Guinea Tigerfish?
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 New Guinea Tigerfish is semi-aggressive (7/10). This notable difference means New Guinea Tigerfish may occasionally assert dominance over Bearded Cory.
Bearded Cory and New Guinea Tigerfish 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.
Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.
Water Parameters
There is no temperature overlap between Bearded Cory (16–23°C) and New Guinea Tigerfish (24–28°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 10–12 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Bearded Cory and New Guinea Tigerfish together, plan for an aquarium of at least 600 litres with a minimum length of 180 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 New Guinea Tigerfish 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 New Guinea Tigerfish.
Frequently Asked Questions
Can Bearded Cory and New Guinea Tigerfish 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 New Guinea Tigerfish need?
A minimum of 600 litres (tank length at least 180 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 New Guinea Tigerfish together?
Unfortunately, there is no temperature range that satisfies both species. Bearded Cory requires 16–23°C, while New Guinea Tigerfish needs 24–28°C.
Are Bearded Cory or New Guinea Tigerfish aggressive?
Bearded Cory is peaceful (2/10) and New Guinea Tigerfish is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.
What pH do Bearded Cory and New Guinea Tigerfish 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 New Guinea Tigerfish's territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives New Guinea Tigerfish 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.
