The Swordtails arrived healthy and active. They have bright colors and swim well in my 50-liter tank. I added some plants and kept the water temperature stable. They seem to be adjusting well and are very lively.

I bought a small group for my community tank. The fish are colorful and active. They don’t seem to fight much, though males do show some chasing behavior. Good for a vibrant touch in a planted aquarium.

Great addition to my aquarium. The fish are easy to care for and stay active. I’ve noticed they breed occasionally, which is a nice sign of healthy development. Water parameters are stable now.
