Rare Gulf Signal Blenny — Emblemaria hypacanthus
The Gulf Signal Blenny is an exceptionally rare nano reef fish prized for its incredible personality, intricate facial markings, and beautiful electric-blue fin displays. Although tiny in size, this species quickly becomes one of the most entertaining fish in the aquarium.
Unlike many blennies, the Gulf Signal Blenny spends much of its day perched at the entrance of a favorite hole or crevice, constantly observing its surroundings before darting out to feed.
Size: Small (Less than 1.25")
