The Koi Tancho Swordtail is a beautiful fish with a unique orange pattern on a white body. It’s active and adds a lot of visual interest to the tank. I kept it in a 10-gallon tank with a mature cycle, and it adjusted quickly. The fish swims gracefully and seems healthy after a few weeks.

I was impressed by how vibrant the fish looks. The orange splashes stand out well in the tank. It’s not aggressive and just enjoys swimming in the middle to upper levels. I recommend it for anyone looking for a colorful, peaceful fish.

The fish arrived safely via UPS Next Day Air. It was in good condition and active right after arrival. I’ve had it for two months now and it’s still very lively. The water parameters match what the seller provided, and it’s thriving.
