Red Red-Eye Lyretail Swordtail
The red red-eye lyre swordtail is a product of an intense breeding program in Asia, and these are the brightest, largest swordtails available. Red-eye lyre swordtails are show quality and require a little salt in the aquarium (one tablespoon to 20 gallons) and can even be kept in brackish conditions. Unlike other swordtails, these fish are difficult to breed, as the females and males both have long veil fins that get in the way of the process. In fact, if not for the gonopodium, it would be difficult to distinguish males from females.

These swordtails are stunning with vibrant red eyes and long tail fins. I added a bit of salt as recommended and they’ve been active and healthy for several months. The color is brighter than standard swordtails I’ve seen before.

The fish arrived quickly and look exactly as described. I kept them in a 20-gallon tank with a small amount of salt. They swim gracefully and are very colorful, though breeding them has been a challenge.

Highly recommended for show tanks. The red-eye coloration is intense and the fins are long and elegant. I’ve kept them in brackish water with success and they seem to thrive.
