About this fish
Diamond Tetra is a beautiful and peaceful community fish admired for its shimmering scales, elegant body shape, and sparkling appearance under aquarium lighting. As they mature, Diamond Tetras develop a stunning reflective sheen that gives them their signature “diamond” look, making them a standout addition to planted aquariums.
This species is best kept in groups, where they feel more secure and display natural schooling behaviour. Diamond Tetras are generally peaceful and suitable for community tanks with other calm species of similar size. They appreciate planted aquariums with open swimming areas, gentle water flow, and stable water conditions.
Their subtle but eye-catching colouration makes them especially attractive in aquascaped tanks, where their reflective scales contrast beautifully against green plants and darker backgrounds.
