Behaviour & Temperament

Agassiz's Dwarf Cichlid is a moderately assertive species (5/10), while Silver Datnoid (Silver Tigerfish) is moderately assertive (6/10). This modest difference means Silver Datnoid (Silver Tigerfish) may occasionally assert dominance over Agassiz's Dwarf Cichlid.

Agassiz's Dwarf Cichlid and Silver Datnoid (Silver Tigerfish) both frequent the Bottom (Substrate) 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 24Β°C and 28Β°C. Aim for the midpoint of this range (around 26.0Β°C) for optimal comfort.

Both fish can tolerate a pH between 7 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Agassiz's Dwarf Cichlid needs 1–8 dGH while Silver Datnoid (Silver Tigerfish) requires 10–25 dGH.

Tank Setup

To house Agassiz's Dwarf Cichlid and Silver Datnoid (Silver Tigerfish) together, plan for an aquarium of at least 450 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), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Plants - Densely covered. 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Agassiz's Dwarf Cichlid and Silver Datnoid (Silver Tigerfish).
