Rainbow Fish

Rainbowfish are vibrant freshwater fish known for their shimmering colors and active schooling behavior. Native to Australia and New Guinea, these fish are prized for their bright metallic bodies that often display shades of blue, red, yellow, and orange depending on the species.

Rainbowfish are very active swimmers and should be kept in groups of at least 6 or more. In larger schools they display their best coloration and natural behavior. They thrive in aquariums with open swimming space, plants, and driftwood while enjoying well-oxygenated water and moderate flow.

These fish are peaceful and do well in community aquariums with other active but non-aggressive species such as tetras, rasboras, danios, and peaceful catfish.
