Naming
It belongs to the large subgenus Rabdophorus which might warrant recognition as a distinct genus. In this group, it almost certainly is a rather close relative of the Threadfin Butterflyfish (C. auriga) and the Indian Vagabond Butterflyfish (C. decussatus).
Behavior
These oviparous, monogamous fish form stable pairs with both pair members jointly defending a feeding territory against other pairs. However they often accompany other species without being aggressive.
Habitat
Chaetodon vagabundus are found in reef flats, lagoons and seaward reefs, and sometimes in turbid waters subject to freshwater runoff.
Food
They are omnivorous, known to feed on algae, coral polyps, crustaceans and worms.
Uses
By the standards of their genus, they are easily maintained in tanks.References:
