Can Banana Loach and Brevis Shelldweller Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 6, 2026
Not Recommended

Banana Loach and Brevis Shelldweller are not recommended as tank mates due to conflicting pH requirements. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Banana Loach and Brevis Shelldweller?

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

Banana Loach is a peaceful species (2/10), while Brevis Shelldweller is moderately assertive (5/10). This modest difference means Brevis Shelldweller may occasionally assert dominance over Banana Loach.

Banana Loach and Brevis Shelldweller 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: Banana Loach 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.

The pH requirements of Banana Loach (6–7.8) and Brevis Shelldweller (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Banana Loach and Brevis Shelldweller together, plan for an aquarium of at least 200 litres with a minimum length of 120 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), Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Usually Fails in Practice

Banana Loach and Brevis Shelldweller 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.

Frequently Asked Questions

Can Banana Loach and Brevis Shelldweller live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Banana Loach and Brevis Shelldweller need?

A minimum of 200 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 Banana Loach and Brevis Shelldweller 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 Banana Loach or Brevis Shelldweller aggressive?

Banana Loach is peaceful (2/10) and Brevis Shelldweller is moderately assertive (5/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Banana Loach and Brevis Shelldweller need?

Their pH requirements do not overlap. Banana Loach prefers 6–7.8, while Brevis Shelldweller needs 8–9. This makes them incompatible in the same water chemistry.

How do I manage Brevis Shelldweller's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Brevis Shelldweller 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 Banana Loach being nocturnal affect compatibility?

Banana Loach 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 Banana Loach during evening hours.
