Silver Hatchetfish – Gasteropelecus levis

Delicate, peaceful, and fascinating to watch, the Silver Hatchetfish (Gasteropelecus levis) is a unique top-dwelling species known for its distinctive hatchet-shaped body and shimmering silver scales. Native to the slow-moving tributaries of South America, these schooling fish add graceful movement and reflective beauty to any peaceful community or planted aquarium.

Their sleek, streamlined shape allows them to glide just below the water’s surface, often darting upward for insects or floating foods. Silver Hatchetfish thrive in calm, well-covered tanks with gentle flow and dim lighting.
