Overview
The Peacock Bass, Cichla ocellaris, is a highly active and territorial species that requires a large, well-planted tank with plenty of space for swimming. They are known for their vibrant colors and striking patterns, making them popular aquarium fish. However, their aggressive nature and size make them unsuitable for most community tanks. Regular water quality maintenance is crucial due to their high metabolisms and sensitivity to poor conditions.
