Blue Tetra by LiveAquaria
The Blue Tetra, also known as Cochu’s Blue Tetra, is an active shoaling fish native to the rivers and streams of the Amazon River Basin in South America. This peaceful community-minded fish is immediately recognized by its breathtakingly beautiful blue coloration. Hints of pink coloration give the Blue Tetra an iridescent, “blushing” sheen that is brought out to maximum effect in setups with darker substrate.
Keep the Blue Tetra in groups of six or more as it is a schooling fish that relishes company. A planted aquarium of at least 20 gallons or larger will provide an ideal environment. A spacious aquarium aquascaped with live plants, rocks, and driftwood replicates its natural habitat and helps reduce stress on this fish.

The Blue Tetras are stunning and very active. I kept them in a 30-gallon tank with live plants and they form a tight school. The pinkish sheen under light is beautiful, especially on dark gravel. They’re peaceful and don’t bother other fish.

I bought six Blue Tetras and they’ve been thriving in my 25-gallon tank. They swim together in a coordinated way and look vibrant. The color changes slightly in different lighting, which is nice to watch.

Great addition to a community tank. They’re easy to care for and don’t require much maintenance. I love how they move through the plants and add visual interest.
