Behaviour & Temperament

Finger Fish is a moderately assertive species (5/10), while Sajica Cichlid (T-Bar Cichlid) is moderately assertive (6/10). This modest difference means Sajica Cichlid (T-Bar Cichlid) may occasionally assert dominance over Finger Fish.

Finger Fish and Sajica Cichlid (T-Bar Cichlid) both frequent the Middle (Open Water) 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 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 12–20 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 Finger Fish and Sajica Cichlid (T-Bar Cichlid) 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: Smooth Gravel (Sensitive Barbels), Sand (Sifters), Driftwood (Digestion/Hiding). 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

Finger Fish and Sajica Cichlid (T-Bar Cichlid) 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 Finger Fish and Sajica Cichlid (T-Bar Cichlid).

Frequently Asked Questions

What water temperature is best for Finger Fish and Sajica Cichlid (T-Bar Cichlid) 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 Finger Fish or Sajica Cichlid (T-Bar Cichlid) aggressive?

Finger Fish is moderately assertive (5/10) and Sajica Cichlid (T-Bar Cichlid) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Finger Fish and Sajica Cichlid (T-Bar Cichlid) need?

Both species overlap in the 7.5–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Will Finger Fish nip Sajica Cichlid (T-Bar Cichlid)'s fins?

Finger Fish is a known fin nipper. If Sajica Cichlid (T-Bar Cichlid) 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.

How do I manage Sajica Cichlid (T-Bar Cichlid)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Sajica Cichlid (T-Bar Cichlid) 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.
