Care notes

Iconic reef fish. Associate symbiotically with anemones (not required). Sequential hermaphrodites; largest fish becomes female. Captive-bred preferred.

Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
