Can your tank handle Reticulated Hillstream Loach and Telmatochromis brichardi?

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

Reticulated Hillstream Loach is a generally mild-mannered species (3/10), while Telmatochromis brichardi is moderately assertive (6/10). This modest difference means Telmatochromis brichardi may occasionally assert dominance over Reticulated Hillstream Loach.

Reticulated Hillstream Loach and Telmatochromis brichardi 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.

Water Parameters

The safe temperature window for both species falls between 24°C and 24°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

The pH requirements of Reticulated Hillstream Loach (6.5–7.5) and Telmatochromis brichardi (8–9.3) 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 Reticulated Hillstream Loach and Telmatochromis brichardi together, plan for an aquarium of at least 80 litres with a minimum length of 90 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: Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Plants - lighly covered, Sand (Sifters), Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Reticulated Hillstream Loach and Telmatochromis brichardi 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 Reticulated Hillstream Loach and Telmatochromis brichardi live together?

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

What size tank do Reticulated Hillstream Loach and Telmatochromis brichardi need?

A minimum of 80 litres (tank length at least 90 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 Reticulated Hillstream Loach and Telmatochromis brichardi together?

Keep the aquarium between 24°C and 24°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Reticulated Hillstream Loach or Telmatochromis brichardi aggressive?

Reticulated Hillstream Loach is generally mild-mannered (3/10) and Telmatochromis brichardi is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Reticulated Hillstream Loach and Telmatochromis brichardi need?

Their pH requirements do not overlap. Reticulated Hillstream Loach prefers 6.5–7.5, while Telmatochromis brichardi needs 8–9.3. This makes them incompatible in the same water chemistry.

How do I manage Reticulated Hillstream Loach's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Reticulated Hillstream Loach 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.
