Can Black Skirt Tetra and Peacock Cichlid (Aulonocara) Live Together?
Keeping Black Skirt Tetra and Peacock Cichlid (Aulonocara) together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 240 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Black Skirt Tetra is a generally mild-mannered species (4/10), while Peacock Cichlid (Aulonocara) is moderately assertive (6/10). This modest difference means Peacock Cichlid (Aulonocara) may occasionally assert dominance over Black Skirt Tetra.
Black Skirt Tetra and Peacock Cichlid (Aulonocara) 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.
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 Black Skirt Tetra and Peacock Cichlid (Aulonocara) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.
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 7.8 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 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Black Skirt Tetra and Peacock Cichlid (Aulonocara) together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Plants - Densely covered, 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.

Are Black Skirt Tetra or Peacock Cichlid (Aulonocara) aggressive?▾
Black Skirt Tetra is generally mild-mannered (4/10) and Peacock Cichlid (Aulonocara) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Black Skirt Tetra and Peacock Cichlid (Aulonocara) need?▾
Both species overlap in the 7.8–8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
Will Black Skirt Tetra nip Peacock Cichlid (Aulonocara)'s fins?▾
Black Skirt Tetra is a known fin nipper. If Peacock Cichlid (Aulonocara) has long or flowing fins, there is a real risk of fin damage. Keeping Black Skirt Tetra in a larger group can help redirect nipping behaviour toward conspecifics.
How do I manage Peacock Cichlid (Aulonocara)'s territorial behaviour?▾
Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Peacock Cichlid (Aulonocara) 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.
