Red Laser Tetra (Hemigrammus coeruleus)
The Red Laser Tetra is a rare and eye-catching nano species that stands out with its glowing red lateral stripe that runs clean through the body like a laser beam. Native to the Amazon Basin, this species combines subtle transparency with intense coloration, creating a stunning contrast that truly pops under proper lighting.
Unlike many common tetras, Hemigrammus coeruleus has a more refined and elegant appearance, making it a perfect addition to high-end planted tanks or display aquariums. When kept in groups, their synchronized schooling behavior creates a mesmerizing “laser line” effect as they move through the water column.
Peaceful and relatively hardy, these fish thrive in well-maintained aquariums with stable water parameters and ample space to swim.

The Red Laser Tetras are absolutely stunning. Their red stripe glows beautifully under LED lighting, and they form a mesmerizing school when active. I keep them in a 20-gallon planted tank with other peaceful fish. They’re active but not aggressive and adapt well to the environment.

I bought a small group and they’ve been thriving for three months. The color is vivid and the schooling behavior is impressive. I use a gentle filter and regular water changes. They don’t require much maintenance but do need stable water conditions.

This is one of the most visually striking tetras I’ve ever seen. The red stripe is sharp and clear, especially in the right lighting. I keep them in a tall tank with live plants, and they swim gracefully through the water column.
