I recently introduced Koi Kohaku Swordtails (Xiphophorus Hellerii) to my aquarium, and I couldn’t be happier! After about two weeks of observing them, I can tell they are not only stunning but also full of personality. The vibrant red and white patterns on their bodies are absolutely eye-catching and they glide gracefully through the water. I’ve noticed them interacting with my other tropical fish, which is a huge plus for my community tank.
Before this, I had plain swordtails, and the difference is night and day! These Koi Kohaku swordtails are more active and curious, making my aquarium come alive. They seem to thrive in my setup, which includes plenty of plants for cover and open swimming space. The shipping was prompt and they arrived healthy, which is always my primary concern when adding new fish.
A minor note to consider is that they can be a bit shy at first, but with time and a little patience, they really warm up to their surroundings. I highly recommend these beauties to any aquarist looking to add vibrant life to their tanks. They would be perfect for both beginner and experienced fish keepers alike. Overall, I’m ecstatic and would definitely buy them again!
