Can Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Cuban Gar Live Together?

Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is a generally mild-mannered species (4/10), while Cuban Gar is moderately assertive (6/10). This modest difference means Cuban Gar may occasionally assert dominance over Barlow's Dwarf Cichlid (Apistogramma Maulbrüter).

Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Cuban Gar 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.

Worth noting: Cuban Gar is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 22°C and 29°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.

Hardness requirements are incompatible: Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) needs 1–5 dGH while Cuban Gar requires 8–20 dGH.

To house Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Cuban Gar together, plan for an aquarium of at least 3785 litres with a minimum length of 300 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), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, 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.

Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Cuban Gar 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.
