The Dispar Anthias, a.k.a. the Redfin or Madder Seaperch, has an orange to yellow body with a dorsal fin marked distinctively in red. In the wild these fish form large groups where they feed on floating plankton.The family of Anthias are closely related to Seabasses, which include Groupers. These fish begin life as females and will change sex based on the requirement of their "harem". Anthias gather in huge schools around reefs where they swim within the school waiting for food. These schools can be seen in the hundreds and are made up of small "harems" of a single dominant male, less dominant males, and many females.
