Care notes
Spectacular color transformation from juvenile (dark with white semicircles) to adult (blue-green). Not reef-safe. Needs a very large aquarium. Territorial with similar species.
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.
