Behaviour & Temperament

Dainty Cory (Salt and Pepper Cory) is a peaceful species (0/10), while Finger Fish is moderately assertive (5/10). This notable difference means Finger Fish may occasionally assert dominance over Dainty Cory (Salt and Pepper Cory).

In terms of spatial distribution, Dainty Cory (Salt and Pepper 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.

Water Parameters

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 12–15 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.

Tank Setup

To house Dainty Cory (Salt and Pepper 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.

Why This Pairing Usually Fails in Practice

Dainty Cory (Salt and Pepper 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Dainty Cory (Salt and Pepper Cory) and Finger Fish.

Frequently Asked Questions

Can Dainty Cory (Salt and Pepper Cory) and Finger Fish live together?

No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.

What size tank do Dainty Cory (Salt and Pepper Cory) and Finger Fish need?

A minimum of 470 litres (tank length at least 150 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 Dainty Cory (Salt and Pepper Cory) and Finger Fish together?

Keep the aquarium between 24°C and 26°C. A target of around 25.0°C sits comfortably within both species' preferred ranges.

Are Dainty Cory (Salt and Pepper Cory) or Finger Fish aggressive?

Dainty Cory (Salt and Pepper Cory) is peaceful (0/10) and Finger Fish is moderately assertive (5/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Dainty Cory (Salt and Pepper Cory) and Finger Fish need?

Both species overlap in the 7.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Finger Fish nip Dainty Cory (Salt and Pepper Cory)'s fins?

Finger Fish is a known fin nipper. If Dainty Cory (Salt and Pepper Cory) has long or flowing fins, there is a real risk of fin damage. Keeping Finger Fish in a larger group can help redirect nipping behaviour toward conspecifics.
