Appearance & Behavior

Growing up to 1.5 inches, the Marbled Hatchetfish features a laterally compressed body covered in marble-like markings that shimmer under aquarium lighting. These fish spend nearly all of their time at the surface, gliding gracefully beneath floating plants and darting in schools when startled. For the best results, keep them in groups of six or more—they’re much more active and confident in schools.
