The redline tetras are incredibly colorful and active. I kept them in a 20-gallon tank with other peaceful community fish. They swim in schools and add a lot of visual interest. Water parameters stayed stable with regular water changes.

These fish are easy to care for and look stunning in a planted tank. I noticed their red stripes become more vibrant in softer water. They don’t stress easily and get along well with my neon tetras.

I’ve had redline tetras for three months now and they’re still active and healthy. The silver-white stripes contrast beautifully with the red. I keep them in a community tank with guppies and dwarf corydoras.
