The swordtails are lively and colorful. I kept them in a 20-liter tank with good water flow and they adapted well. They swim actively and add a lot of visual interest. Feeding them flakes and live foods works well.

They are active and vibrant. I noticed they do get a bit territorial when there are multiple males. I keep them with peaceful species and maintain a good water change schedule.

Great addition to my community tank. The red color stands out and they stay active even in a smaller setup. I feed them daily and they seem healthy and energetic.
