The peacock eye cichlid is a South American fish that comes from the Amazon.

This cichlid species prefers calm, stagnant waters; it often stays in dead tributaries of rivers.

There you can often find it at the bottom.

Normally peacock eye cichlids are calm animals.

But they can become very aggressive towards each other or other fish.

“Everything that fits into the mouth is eaten” is the basic rule for the coexistence of peacock eye cichlids with other fish species.
