The Lavender Tang is often passed over by hobbyists since it's not quite as striking at first glance like many of the other readily available tangs. But, once you fatten the Lavender Tang up and get them under the right lighting the colors on these Lavenders can really come to life. Lavender Tangs have light gray bodies with pastel like yellow dorsal fins and purple tail/anal fins. They also have small yellow dots on their mouth and face.
