Can False Glass Catfish and Telmatochromis dhonti Live Together?

False Glass Catfish is a peaceful species (2/10), while Telmatochromis dhonti is semi-aggressive (8/10). This notable difference means Telmatochromis dhonti may occasionally assert dominance over False Glass Catfish.

Large aggression gap (6 points) between False Glass Catfish and Telmatochromis dhonti increases stress risk for the more peaceful fish.

In terms of spatial distribution, False Glass Catfish prefers the Middle (Open Water) zone, whereas Telmatochromis dhonti 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.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species.

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 False Glass Catfish (5–7) and Telmatochromis dhonti (7.8–9) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: False Glass Catfish needs 1–8 dGH while Telmatochromis dhonti requires 10–25 dGH.

To house False Glass Catfish and Telmatochromis dhonti together, plan for an aquarium of at least 120 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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Sand (Sifters), 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.

False Glass Catfish and Telmatochromis dhonti 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.
