I recently purchased the 6 x Koi Kohaku Swordtails, and I couldn’t be happier! As a caring fish parent, my top priority is the well-being of my aquatic friends, and these livebearers have truly exceeded my expectations. They arrived in perfect condition, vibrant and energetic, which was a relief after my previous experience with another seller.
After just a week in my 55-gallon freshwater setup, they adapted wonderfully to the environment. The colors are stunning, and I love watching them interact with the other fish. They’re active swimmers, and their playful nature has brought my aquarium to life!
Compared to the other swordtails I’ve kept, the Kohaku variety stands out not just for their striking appearance but also for their hardiness. They’ve demonstrated a great level of adaptability, making them perfect for both beginners and seasoned aquarists alike. The only minor concern is that they can be a little nippy during feeding time, but that’s pretty typical for swordtails.
If you’re looking for lively, beautiful tropical fish that will thrive in your aquarium, I wholeheartedly recommend these Kohaku Swordtails. I’ll definitely be purchasing more in the future!
