Black Nubian Swordtail
Black Nubian swordtails have solid black bodies with black and clear fins. With the clear and black color of the tail, these fish really do look like they are dragging swords. Black Nubian swordtails look great against green plants and reflect light with an iridescent sheen. We recommend the purchase of at least one pair, male and female. Pairs will tend to stay together as they swim about the tank.

Perfect for a small community tank. The fish are hardy and don’t require much attention. They look like they’re dancing in the water, which is very entertaining.
