More Info


Known only from the Lord Howe Island region and Elizabeth and Middleton Reefs, in the Tasman Sea (Australia), and at Raoul Island in the Kermadec Islands (northern New Zealand). Inhabits deep outer reef slopes on coral and rocky reefs in depths of 10-100 m, usually below 35 m.


Usually occurs in a small harem with a male and up to 4 females. If the male disappears, the dominant female will change sex and colour pattern over a period of several weeks.


The Halfbanded Angelfish is reportedly fairly common at Balls Pyramid near Lord Howe Island.
