Can Bearded Cory and Finger Fish Live Together?

Bearded Cory is a peaceful species (2/10), while Finger Fish is moderately assertive (5/10). This modest difference means Finger Fish may occasionally assert dominance over Bearded Cory.

In terms of spatial distribution, Bearded Cory prefers the Bottom (Substrate) zone, whereas Finger Fish occupies the Middle (Open Water) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

There is no temperature overlap between Bearded Cory (16–23°C) and Finger Fish (24–28°C). This fundamental mismatch makes long-term cohabitation impractical.

The pH requirements of Bearded Cory (6–7.4) and Finger Fish (7.5–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 12–12 dGH. Regular testing will ensure conditions stay within this range.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

To house Bearded Cory and Finger Fish together, plan for an aquarium of at least 470 litres with a minimum length of 150 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). 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.

Bearded Cory and Finger Fish 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.
