The Ruby Tetra is a stunning addition to my 10-gallon planted tank. It’s tiny but vibrant, and it swims gracefully among the plants. Very easy to keep and doesn’t stress other fish. I’ve had it for three months and it’s still active and healthy.

I love how colorful the Ruby Tetra is. It’s much smaller than other tetras, so it fits perfectly in my nano setup. The fish are calm and don’t chase each other. Just make sure the tank has some plants for cover.

This is one of the best small tetras I’ve ever added to my aquarium. It blends well with my live plants and doesn’t compete for space. The fish are active but not aggressive, making it ideal for a community tank.
