These freshwater hatchetfish are . Their mouths are situated on the top of their bodies for feeding on the surface. These fish will normally not eat anything that falls below them as they are strictly surface feeders and can only see what is above them. In the wild, they will eat foods such as small vinegar flies and mosquito larvae.In the aquarium, Marbled Hatchetfish will generally eat all kinds of foods as long as the food is on the surface of the water. They will not survive on just a flake food. To keep a good balance, give them a protein such as Black mosquito larvae, fruit flies, blood worms, or brine shrimp (either live or frozen) every day. The foods fed to these fish need to stay at the surface longer than most.
There are nine species of freshwater hatchetfish from three genera: Carnegiella, Gasteropelecus, and Thoracocharax.

Hatchetfish are some of the more unique looking fish species available to freshwater hobbyists. They get to a couple of inches in size and some have the ability to fly or jump out of the water. They are a top dwelling fish and along with their known jumping habits an aquarium with a tight fitting hood is definitley needed to keep them from carpet surfing.Black-winged Hatchetfish (Carnegiella marthae) …a species of freshwater hatchetfish (Gasteropelecidae) that is native to South America, Primarily the Rio Negro and the Orinoco. Like other freshwater hatchetfish C. marthae lives close to the water’s surface and feed mainly insects, which are caught by jumping and gliding out of the water.The common hatchetfish (Gasteropelecus sternicla), also known as the river hatchetfish, and the silver hatchetfish, is a freshwater fish with a uniquely shaped body. However, the name silver hatchetfish is actually a misnomer, and should be used instead to describe . The name hatchetfish originates from its laterally compressed body, which resembles the head of a hatchet.This species spends almost all of its time at or just below the water surface, although it will sometimes retreat into midwater if threatened or feeding. Like other freshwater hatchetfishes, it is renowned for its ability to leap from the water surface and glide for distances of several metres. This behaviour is used both to catch flying insects, and to escape potential predators.Gasteropelecids are commonly-referred to as ‘freshwater hatchetfishes’ due to their heavily-keeled body shape which has evolved in such a way due to possessing an enlarged, heavily-muscled pectoral girdle, and which resembles the shape of a hatchet head.Gasteropelecids are commonly-referred to as ‘freshwater hatchetfishes’ due to their heavily-keeled body shape which has evolved in such a way due to possessing an enlarged, heavily-muscled pectoral girdle, and which resembles the shape of a hatchet head.
