Santa Claus (Koi) Swordtail

Santa Claus (Koi) Swordtail

Lovingly named due to its bright orange head, shimmery white body and sharp tail fin, the Santa Claus Swordtail or Xiphophorus helleri are a rare freshwater species with fascinating Koi-like colorations. Its unique appearance and peaceful disposition make it a perfect choice for all aquarists. Swordtails can grow up to three inches long but due to their longer fin, it’s best to avoid pairing your Swordtail with other fin-nipping species.

What Are Santa Claus Swordtail Like?

The Santa Claus Swordtail is an ever-popular choice due to its striking appearance, peaceful disposition, and adaptable nature. They are naturally sociable and prefer to live in groups, thriving best in community aquariums where no tiny fish are present. Male Santa Claus Swordtails can become competitive so we recommend limiting numbers in comparison to females to prevent squabbles.

Who Is Suited To Santa Claus Swordtail?

Hardy and adaptable, this unique Swordtail can be a great option for both beginners and intermediate hobbyists. They are very undemanding creatures, easy to care for, and can be kept in community aquariums. Growing to around three inches long, Swordtails are a convenient size for both small and large tanks.

The Ideal Aquarium Conditions For A Santa Claus Swordtail

Indigenous to Mexico and Central America, the Santa Claus Swordtail is typically found in fast-flowing streams, springs, and rivers with diffused light. Their tank doesn’t require much vegetation however they do appreciate floating plants and wood structures to dim direct lighting, making them feel more comfortable. Ensure your water is highly oxygenated and the tank has a secure lid.

Santa Claus (koi) swordtails!

Received my order last week from Flip Aquatics that included Santa Claus swordtails. Very beautiful and healthy fish! They were packed very well, and I received the ratio of males/females that I asked for. They really pop in my tank with their contrasting vibrant red and white! Great experience and I will definitely order from Flip again.
