🐟 Sunset Swordtail (Xiphophorus hellerii)
A Warm Gradient Blending Orange, Red, and Yellow Tones • Reminiscent of a Sunset Across the Body • A Hardy, Easy Livebearer for Any Community Tank
📋 The Sunset Swordtail has a warm gradient of colour blending orange, red, and yellow tones across the body, reminiscent of a sunset, a striking selectively bred variety of the classic Swordtail.
Like nearly every colour variety in the hobby, this gradient pattern is the product of generations of selective breeding, rather than something found in the wild olive-green-to-brown original form. It comes from Central America, from Mexico down to Honduras. Every Sunset Swordtail we ship is feeding well.
This is a true livebearer, giving birth to fully formed, free-swimming fry rather than laying eggs. Males develop the species' signature sword-shaped tail extension as they mature; females do not. It's a hardy, easy community fish, though males can spar with each other, so keeping more females than males in a group helps keep things calm. It's also a known jumper, so a secure lid matters. It reaches up to 14cm including the sword, so a 100L tank suits it well.
