Can your tank handle Angelicus Pleco L073 and Peacock Cichlid (Aulonocara)?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Angelicus Pleco L073 is a generally mild-mannered species (3/10), while Peacock Cichlid (Aulonocara) is moderately assertive (6/10). This modest difference means Peacock Cichlid (Aulonocara) may occasionally assert dominance over Angelicus Pleco L073.

Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) 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.

Worth noting: Angelicus Pleco L073 is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

Water Parameters

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

The pH requirements of Angelicus Pleco L073 (5.5–7.5) and Peacock Cichlid (Aulonocara) (7.8–8.6) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) together, plan for an aquarium of at least 200 litres with a minimum length of 120 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: Driftwood (Digestion/Hiding), Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.

Why This Pairing Usually Fails in Practice

Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) 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.

Frequently Asked Questions

Can Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) need?

A minimum of 200 litres (tank length at least 120 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) together?

Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.

Are Angelicus Pleco L073 or Peacock Cichlid (Aulonocara) aggressive?

Angelicus Pleco L073 is generally mild-mannered (3/10) and Peacock Cichlid (Aulonocara) is moderately assertive (6/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Angelicus Pleco L073 and Peacock Cichlid (Aulonocara) need?

Their pH requirements do not overlap. Angelicus Pleco L073 prefers 5.5–7.5, while Peacock Cichlid (Aulonocara) needs 7.8–8.6. This makes them incompatible in the same water chemistry.

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.

Does Angelicus Pleco L073 being nocturnal affect compatibility?

Angelicus Pleco L073 is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Angelicus Pleco L073 during evening hours.
