Silver Hatchetfish

Silver Hatchetfish (Gasteropelecus Levis)

Silver Hatchetfish, also known as Silver Hatchet, are captivating freshwater fish known for their unique body shape and fascinating ability to glide above the water's surface. Featuring a convex body with a fairly straight back and small ventral fins, these fish boast transparent, wing-like pectoral fins that often measure up to half of their total body length. Their coloration is silver to white with an olive-brown hue on the back. Depending on the angle of light, iridescent green or blue colors may be visible. A vertical green-to-yellow stripe extends from the gill cover to the base of the tail.

These peaceful fish make them great additions to a community tank. They are best kept in schools of at least 6-8 individuals and reach an adult size of approximately 2.5 inches. These fish are surface dwellers, preferring the top level of the aquarium.

Several slower swimming, middle-dwelling community fish can be paired with the timid nature of Silver Hatchetfish. Suitable tank mates include Dwarf Gouramis, Neon Tetras, Rummy Nose Tetras, Harlequin Rasboras, Pencilfish, and Corydoras catfish. It is important to avoid faster swimming fish like Danios or Barbs, as they may outcompete the Silver Hatchetfish for food and cause unnecessary stress.

Their diet consists of small insects, larvae, and other invertebrates, but they will also accept crushed flake foods and small, floating pellets, small live or frozen foods like daphnia and brine shrimp, and freeze-dried foods.

Silver Hatchetfish thrives in a heavily-planted tank with plenty of hiding spaces provided by floating plants or driftwood on the surface and ample swimming space. Dim lighting, a gentle water flow, and a dark substrate will help them feel more secure and display their best colors.

Silver Hatchetfish thrive in well-planted aquariums with a minimum size of 20 gallons, though a larger community tank of 30 gallons or more is ideal. The water parameters should be maintained within a pH range of 6.0-7.5, a hardness of 5-15 dGH, and a temperature of 74-82°F (23-28°C). Excellent water quality must be maintained to keep this fish at its best.
