Swordtail – Koi Lyretail
Swordtail fish (Xiphophorous hellerii) are a very popular community aquarium fish. Their popularity stems from their ease of care and peaceful nature. They have quite unique types of fins with a great variety of colors, making them commonly referred to as BLACK swordtails.
In captivity, swordtail has been selectively interbred, resulting to a wider range of mixtures of colours. The name swordtail gives justice to its appearance – specifically, the male’s appearance. The male’s caudal fin protrudes along its lower half, the length of which can reach up to half of the body’s entire length. The female caudal fin has no such protrusion.

I bought a male swordtail for my 20-gallon tank. It’s very active and adds a lot of visual interest. The colors are vibrant and it’s easy to care for. I’ve had it for three months and it’s still healthy and lively.
