Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Silver Dollar and Telmatochromis brichardi 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 Silver Dollar 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

Silver Dollar is a peaceful species (2/10), while Telmatochromis brichardi is moderately assertive (6/10). This notable difference means Telmatochromis brichardi may occasionally assert dominance over Silver Dollar.

In terms of spatial distribution, Silver Dollar prefers the Middle (Open Water) and Top (Surface) zones, whereas Telmatochromis brichardi occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Silver Dollar is a known jumper, so a tight-fitting lid is essential.

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 Silver Dollar (5.5–7.5) 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 Silver Dollar and Telmatochromis brichardi together, plan for an aquarium of at least 280 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: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Sand (Sifters), Shells (Breeding/Hiding), Established Algae (Otocinclus). 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

Silver Dollar 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 Silver Dollar 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 Silver Dollar and Telmatochromis brichardi need?

A minimum of 280 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 Silver Dollar and Telmatochromis brichardi 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 Silver Dollar or Telmatochromis brichardi aggressive?

Silver Dollar is peaceful (2/10) and Telmatochromis brichardi is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Silver Dollar and Telmatochromis brichardi need?

Their pH requirements do not overlap. Silver Dollar prefers 5.5–7.5, while Telmatochromis brichardi needs 8–9.3. This makes them incompatible in the same water chemistry.
