Peacock Cichlids are among the most colorful African cichlids in the aquarium hobby. Their bright blues, reds, oranges, and yellows make them a centerpiece fish in many freshwater aquariums. Unlike some aggressive cichlids, Peacock Cichlids are considered moderately aggressive, which makes them easier to keep in community setups with the right species.
However, not every fish can live peacefully with Peacock Cichlids. They still show territorial behavior, especially when competing for food or space. Choosing compatible tank mates helps prevent fighting and keeps the aquarium balanced. In this guide, you’ll learn which fish work best with Peacock Cichlids, which species to avoid, and how to create a peaceful African cichlid aquarium.

Peacock Cichlid Behavior
Before choosing tank mates, it helps to understand how Peacock Cichlids behave in an aquarium.
Temperament of Peacock Cichlids
Peacock Cichlids are less aggressive than many other African cichlids, but they are still territorial. Males especially may chase other fish when defending their space.
Social Structure
These fish do well in groups. Many aquarists keep one male with several females to reduce aggression.
Habitat Preference
Peacock Cichlids come from Lake Malawi, where they live among sandy bottoms with scattered rocks. Replicating this environment in the aquarium helps them feel secure.
What Makes a Good Tank Mate for Peacock Cichlids
A suitable tank mate should share similar water conditions and temperament.
Similar Water Parameters
Peacock Cichlids prefer:
- pH: 7.5–8.5
- Hard water
- Warm temperatures around 76–82°F
Tank mates should tolerate the same conditions.
Semi-Aggressive Fish
Peaceful fish may become targets, while extremely aggressive species may cause constant fights.
Similar Size
Fish that are too small can be bullied or eaten.
Fast or Active Swimmers
Fish that move quickly tend to avoid aggression more easily.
Best Peacock Cichlid Tank Mates
These species are commonly kept with Peacock Cichlids in well-maintained aquariums.
Haplochromis (Haps)
Haps are one of the most popular companions for Peacock Cichlids. They come from the same lake and share similar water requirements. Many species are colorful and moderately aggressive.
Examples include:
- Electric Blue Hap
- Red Empress Cichlid
- Sunshine Peacock relatives
Other Peacock Cichlids
Many aquarists keep multiple Peacock species together. A group of different colored males and females creates a vibrant African cichlid display tank.
To reduce aggression, keep more females than males.
Yellow Lab Cichlids
Yellow Labs are among the most peaceful African cichlids. Their bright yellow color contrasts beautifully with Peacock Cichlids, making them a popular combination.
They also share similar water conditions.
Synodontis Catfish
Synodontis catfish are hardy bottom dwellers that do well in African cichlid aquariums. They spend most of their time near the bottom and rarely compete with cichlids.
Their armored bodies also help them tolerate occasional aggression.
Plecos
Large Plecos can live with Peacock Cichlids because they stay on the bottom and avoid territorial disputes. They also help control algae growth.
Choose larger species, as small plecos may be bullied.
Giant Danios
Giant Danios are fast swimming fish that stay near the top of the tank. Their speed allows them to avoid aggressive interactions.
They are sometimes used as dither fish, helping reduce cichlid aggression.
Tank Mates to Avoid With Peacock Cichlids
Some fish simply do not mix well with Peacock Cichlids.
Small Tetras
Tiny schooling fish like neon tetras can become easy targets.
Guppies and Other Livebearers
Peaceful fish such as guppies are not suited for African cichlid tanks.
Aggressive Mbuna Cichlids
Mbuna cichlids from Lake Malawi are extremely territorial. Mixing them with Peacock Cichlids often leads to constant fighting.
Angelfish
Angelfish prefer softer water and calmer environments, which makes them incompatible with Peacock Cichlid tanks.
Ideal Tank Setup for Peacock Cichlid Community Tanks
Creating the right environment helps fish live together peacefully.
Tank Size
For a Peacock Cichlid community tank:
- Minimum: 55 gallons
- Ideal: 75 gallons or larger
More space helps reduce territorial disputes.
Rock Structures and Hiding Spots
African cichlids love rocky environments. Use stacked rocks and caves to create natural territories.
Sandy Substrate
Peacock Cichlids naturally sift sand when searching for food. Sand substrates help mimic their natural habitat.
Strong Filtration
Cichlids produce a lot of waste, so powerful filtration is essential for maintaining water quality.
Tips for Keeping Peacock Cichlids Peacefully
Keep More Females Than Males
This helps spread out aggression and reduces competition.
Avoid Mixing Extremely Aggressive Fish
Stick with moderately aggressive species.
Add Fish Together
Introducing fish at the same time prevents one species from claiming the entire tank.
Provide Plenty of Space
A larger aquarium dramatically improves compatibility.
