Can Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) Live Together?
Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) are not recommended as tank mates due to conflicting pH requirements and incompatible hardness ranges. 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 Incolicana Corydoras and Silver Tiger Perch (American 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
Incolicana Corydoras is a peaceful species (1/10), while Silver Tiger Perch (American Tigerfish) is semi-aggressive (7/10). This notable difference means Silver Tiger Perch (American Tigerfish) may occasionally assert dominance over Incolicana Corydoras.
Large aggression gap (6 points) between Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) increases stress risk for the more peaceful fish.
Incolicana Corydoras and Silver Tiger Perch (American 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.
Water Parameters
The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.
The pH requirements of Incolicana Corydoras (5–7.2) and Silver Tiger Perch (American Tigerfish) (7.5–9) do not overlap, making it impossible to satisfy both species simultaneously.
Hardness requirements are incompatible: Incolicana Corydoras needs 2–12 dGH while Silver Tiger Perch (American Tigerfish) requires 15–30 dGH.
Tank Setup
To house Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) together, plan for an aquarium of at least 650 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), Smooth Gravel (Sensitive Barbels), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
Why This Pairing Usually Fails in Practice
Incolicana Corydoras and Silver Tiger Perch (American 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 Incolicana Corydoras and Silver Tiger Perch (American Tigerfish).
Frequently Asked Questions
Can Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) need?
A minimum of 650 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 Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) together?
Keep the aquarium between 22°C and 26°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.
Are Incolicana Corydoras or Silver Tiger Perch (American Tigerfish) aggressive?
Incolicana Corydoras is peaceful (1/10) and Silver Tiger Perch (American 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 Incolicana Corydoras and Silver Tiger Perch (American Tigerfish) need?
Their pH requirements do not overlap. Incolicana Corydoras prefers 5–7.2, while Silver Tiger Perch (American Tigerfish) needs 7.5–9. This makes them incompatible in the same water chemistry.
How do I manage Silver Tiger Perch (American Tigerfish)'s territorial behaviour?
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Silver Tiger Perch (American 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.
