[3] It has a wide range from the Red Sea to South Africa and as far east as southern Japan and Hawaii.

These four differ wildly in shape, but all have bluish vertical lines on a white body with yellow behind, and black on back and caudal peduncle in addition to the typical eyestripe of Chaetodon.

The blue-cheeked butterflyfish (C. semilarvatus) seems to be a far more basal lineage of Rabdophorus relative to them, but it also has the tell-tale blue vertical lines.

[2] Coral polyps, small anemones, algae and invertebrates make up the lined butterflyfish's diet.

Lined butterflyfish are social maters, meaning they spend time with their mate outside of just spawning often living together in the same habitat.

However, upon further investigation it seems that C. lineolatus and other corallivore members of Chaetodontidae pose a bigger threat to coral than previously understood.

[13] The species is classified as Least Concern by the IUCN due to its wide distribution and presence in protected areas.
