Behaviour & Temperament

Both Senegal Bichir and Shell Dweller (Multi) are moderately assertive species with an aggression score of 6/10. Their matching temperaments mean neither fish is likely to dominate the other in a shared aquarium.

Senegal Bichir and Shell Dweller (Multi) 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.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Senegal Bichir and Shell Dweller (Multi) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

Water Parameters

The safe temperature window for both species falls between 25°C and 27°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.8 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 10–20 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

Tank Setup

To house Senegal Bichir and Shell Dweller (Multi) together, plan for an aquarium of at least 240 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Shells (Breeding/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.

Frequently Asked Questions

Can Senegal Bichir and Shell Dweller (Multi) live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 240 litres), plenty of hiding spots, and watch for signs of stress or aggression.

What size tank do Senegal Bichir and Shell Dweller (Multi) need?

A minimum of 240 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 Senegal Bichir and Shell Dweller (Multi) together?

Keep the aquarium between 25°C and 27°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Senegal Bichir or Shell Dweller (Multi) aggressive?

Senegal Bichir is moderately assertive (6/10) and Shell Dweller (Multi) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Senegal Bichir and Shell Dweller (Multi) need?

Both species overlap in the 7.8–7.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

How do I manage Shell Dweller (Multi)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Shell Dweller (Multi) 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 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.
