Paddlefin Wrasse (Female)

Also known as Paddle-Fin Wrasse (Female), Thalassoma variant

The female Paddlefin Wrasse is an active, colorful species typically featuring yellow, green, or blue-green base coloration with streamlined body shape. Females are generally smaller and less boldly colored than males but still attractive and entertaining. This hardy, active wrasse is suitable for larger community tanks and is less aggressive than males. Like all Thalassoma wrasses, females are extremely active swimmers requiring substantial open water space.
