Maintain these water conditions for optimal health and vibrant colors
Koi Tricolour Swordtail is a colourful domestic swordtail strain with orange, white and black koi-style patterning. It is a Xiphophorus hellerii livebearer, so it needs more swimming room than many platies and does best in stable hard-water community aquariums.
Use a covered aquarium with steady filtration, plant cover and open swimming lanes. Good tank mates include peaceful livebearers and calm community fish that tolerate similar hard, neutral-to-alkaline water. Avoid fin nippers and cramped nano setups.
Livestock is packed for overnight travel with a licensed live-animal courier and covered by our Live Arrival Guarantee.
