🐟 Kohaku Swordtail (Xiphophorus hellerii)
A Clean White Body With Bold Red Patches, Like a Kohaku Koi • A Striking, Selectively Bred Colour Variety • A Hardy, Easy Livebearer for Any Community Tank
📋 The Kohaku Swordtail has a clean white body marked with bold red patches, the classic red-and-white pattern of a Kohaku koi, with no two fish marked exactly alike.
Like nearly every colour variety in the hobby, this red-and-white 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 Kohaku 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.
