Can Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Scarlet Badis Live Together?

Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is a generally mild-mannered species (4/10), while Scarlet Badis is generally mild-mannered (3/10). This modest difference means Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) may occasionally assert dominance over Scarlet Badis.

Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Scarlet Badis both frequent the Bottom (Substrate) and 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.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks. Shrimp eaters may also prey on very small nano fish.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Scarlet Badis to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

The safe temperature window for both species falls between 22°C and 26°C. Aim for the midpoint of this range (around 24.0°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.

For general hardness, the shared comfort zone is 4–5 dGH. Regular testing will ensure conditions stay within this range.

To house Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Scarlet Badis together, plan for an aquarium of at least 54 litres with a minimum length of 60 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Plants - Densely covered, Plants - lighly covered. 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.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) and Scarlet Badis need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Feeding time deserves special attention with this pairing. Barlow's Dwarf Cichlid (Apistogramma Maulbrüter) is a known shrimp eater and may prey on small invertebrates or nano fish like Scarlet Badis.
