Can Scat (Brackish) and Senegal Bichir Live Together?
Scat (Brackish) and Senegal Bichir are not recommended as tank mates due to incompatible water types. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.
At a Glance
Behaviour & Temperament
Scat (Brackish) is a generally mild-mannered species (4/10), while Senegal Bichir is moderately assertive (6/10). This modest difference means Senegal Bichir may occasionally assert dominance over Scat (Brackish).
Scat (Brackish) and Senegal 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: Senegal Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Senegal Bichir is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.
Both fish can tolerate a pH between 7.5 and 7.8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 12–20 dGH. Regular testing will ensure conditions stay within this range.
Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.
Tank Setup
To house Scat (Brackish) and Senegal Bichir together, plan for an aquarium of at least 540 litres with a minimum length of 150 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.
Scat (Brackish) prefers High (River/Stream) flow while Senegal Bichir needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
Frequently Asked Questions
Can Scat (Brackish) and Senegal Bichir live together?▾
No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.
What size tank do Scat (Brackish) and Senegal Bichir need?▾
A minimum of 540 litres (tank length at least 150 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 Scat (Brackish) and Senegal Bichir together?▾
Keep the aquarium between 25°C and 28°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.
Are Scat (Brackish) or Senegal Bichir aggressive?▾
Scat (Brackish) is generally mild-mannered (4/10) and Senegal Bichir is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Scat (Brackish) and Senegal Bichir need?▾
Both species overlap in the 7.5–7.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Scat (Brackish) nip Senegal Bichir's fins?▾
Scat (Brackish) is a known fin nipper. If Senegal Bichir has long or flowing fins, there is a real risk of fin damage. Keeping Scat (Brackish) in a larger group can help redirect nipping behaviour toward conspecifics.
Does Senegal Bichir being nocturnal affect compatibility?▾
Senegal 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 Senegal Bichir during evening hours.
