Peppermint Angelfish (referred to in-game as Peppermint Angel), is a species of angelfish in Abyssrium. It was added in the 1.1.8 version.
To unlock Peppermint Angel, you must own at least 30 Angelfish of any type. For these purposes, the Moorish Idol also counts as an Angelfish. Fusion Angelfish may also count.
The peppermint angelfish is found in the eastern-central Pacific around the Cook Islands and Rarotonga. It is a shy species hiding amongst rocks and rubble of reef cliffs. Centropyge boylei is occasionally exported as an aquarium specimen and can fetch high prices (a single specimen was offered to be bought for $30,000).
