About Doubletooth Soldierfish

Doubletooth Soldierfish are moderately sized fish with a deep, compressed body shape and large eyes adapted for low-light reef environments. They display reddish to silvery coloration with distinctive double teeth (giving the species its name), and black edges on their dorsal and anal fins are characteristic of the species.
