Can Leopard Bushfish (Ctenopoma) and Severum Live Together?
Yes, Leopard Bushfish (Ctenopoma) and Severum are ideal tank mates. Both species share compatible water parameters and peaceful temperaments, making them well-suited for a community aquarium. A minimum tank size of 336 litres is recommended.
At a Glance
Behaviour & Temperament
Leopard Bushfish (Ctenopoma) is a generally mild-mannered species (4/10), while Severum is moderately assertive (5/10). This modest difference means Severum may occasionally assert dominance over Leopard Bushfish (Ctenopoma).
Leopard Bushfish (Ctenopoma) and Severum 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.
Worth noting: Leopard Bushfish (Ctenopoma) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.
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 Severum together, plan for an aquarium of at least 336 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.
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: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Severum is a plant destroyer, which conflicts with Leopard Bushfish (Ctenopoma)'s requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

What size tank do Leopard Bushfish (Ctenopoma) and Severum need?▾
A minimum of 336 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 Severum 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 Severum aggressive?▾
Leopard Bushfish (Ctenopoma) is generally mild-mannered (4/10) and Severum is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Leopard Bushfish (Ctenopoma) and Severum 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.
How do I manage Severum's territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Severum 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.
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.
