Key identification features
- Compact, oval, laterally compressed body up to about 15 cm
- Silvery-white body crossed by two broad black vertical bands: one through the eye, one across the mid-body
- Black band running across the base of the dorsal fin and into the tail region
- Fins washed with pale yellow, dorsal fin often black-tipped
- No eyespot present near the tail base
- Steeply sloped forehead giving a slightly angular profile
Common look-alikes
- Foureye Butterflyfish (Chaetodon capistratus): has only a single eye bar plus a separate white-ringed eyespot near the tail, rather than a second broad body band.
- Spotfin Butterflyfish (Chaetodon ocellatus): shows just one eye bar and a black spot on the dorsal fin, without any second vertical band across the body.
Where you'll see one
This species occurs throughout the western Atlantic, Caribbean, and Gulf of Mexico on coral and rocky reefs, typically in pairs, picking at coral polyps and small invertebrates along reef structure. Bonded pairs tend to defend a shared feeding territory and can often be found returning to the same patch of reef day after day.
Frequently asked questions
How do I tell a Banded Butterflyfish from a Foureye Butterflyfish?
Count the dark bands: the Banded Butterflyfish shows two broad black vertical bands and no tail spot, while the Foureye Butterflyfish has just one eye bar plus a distinct white-ringed eyespot near the tail.
What is the most reliable mark for spotting this species?
Two bold black bands, one through the eye and one at mid-body, on an otherwise plain silvery-white fish is the clearest way to confirm a Banded Butterflyfish.
