Can Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha Live Together?
Keeping Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha together is possible but requires caution due to differing aggression levels and potential behavioral clashes. Provide a spacious tank of at least 456 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Leopard Bushfish (Ctenopoma) is a generally mild-mannered species (4/10), while Red-Bellied Piranha is semi-aggressive (8/10). This notable difference means Red-Bellied Piranha may occasionally assert dominance over Leopard Bushfish (Ctenopoma).
Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha both frequent the Middle (Open Water) and 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: Aggressive fish may bully and stress shy, slow-moving species.
Worth noting: Leopard Bushfish (Ctenopoma) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.
Water Parameters
The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.
Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha together, plan for an aquarium of at least 456 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater. 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.

Frequently Asked Questions
Can Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha live together?▾
They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 456 litres), plenty of hiding spots, and watch for signs of stress or aggression.
What size tank do Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha need?▾
A minimum of 456 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 Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha together?▾
Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.
Are Leopard Bushfish (Ctenopoma) or Red-Bellied Piranha aggressive?▾
Leopard Bushfish (Ctenopoma) is generally mild-mannered (4/10) and Red-Bellied Piranha 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 Leopard Bushfish (Ctenopoma) and Red-Bellied Piranha need?▾
Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Does Leopard Bushfish (Ctenopoma) being nocturnal affect compatibility?▾
Leopard Bushfish (Ctenopoma) 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 Leopard Bushfish (Ctenopoma) during evening hours.
