Emperor kerri blue/purple

The Kerri Blue Tetra, also known as the Purple Emperor Tetra, is a stunning mid?water schooling fish known for its shimmering blue?violet body and elegant, elongated fins. Their subtle metallic glow makes them stand out beautifully in planted aquariums, especially under soft or natural?tone lighting.

Peaceful and active, Kerri Blues thrive in groups of six or more, where their colours deepen and their natural shoaling behaviour becomes more visible. They mix well with other calm community species such as rasboras, small tetras, corydoras, and peaceful dwarf cichlids.

These hardy fish prefer soft to neutral water, gentle flow, and a well?planted environment with open swimming space. A varied diet of quality flakes, micro?pellets, and frozen foods keeps them vibrant and healthy.

Perfect for aquarists looking to add a splash of refined colour and movement to a community setup.
