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.

Key facts

Doubletooth Soldierfish require moderate care due to their need for stable water conditions, adequate space, and proper feeding. They are nocturnal and can be aggressive with smaller fish or shrimp, so tankmate selection is important.
