Singular Bannerfish

Heniochus singularis is a spectacular member of the butterflyfish family Chaetodontidae that delivers a graphic visual punch while boasting ease of care. Similar to other members of the genus Heniochus, the Singular Bannerfish sports a lengthened dorsal ray that gives it a distinct and instantly recognizable banner-like profile.

Description

The Singular Bannerfish is distinguished from other Bannerfish by specific banding patterns. The Singular Bannerfish has a white ring around the mouth followed by a sequence of black bands including a complete ocular band that originates above and extending beyond the eye down to its "chin." The following black, mid-body band is located in front of the dorsal fin and the final black band transitions seamlessly to a bold, canary yellow coloration that follows the dorsal ridge and caudal fin.

Juvenile and adult Singular Bannerfish vary in appearance, most notably the longer white "banner" of juvenile Singular Bannerfish that accentuates the angular, deltoid body shape. Mature adults have a short banner and take on a fuller body shape more closely resembling the classic Butterflyfish body shape. Furthermore, adult Singular Bannerfish sports an exquisite reticulated pattern not dissimilar to that of the highly prized Wrought Iron Butterflyfish. As the largest member of the Bannerfish, the Singular Bannerfish makes an impressive display, singularly or in a small group.
