Marine Hatchetfish
Marine hatchetfishes or deep-sea hatchetfishes are small deep-sea mesopelagic ray-finned fish of the stomiiform subfamily Sternoptychinae. They should not be confused with the freshwater hatchetfishes, which are not particularly closely related Teleostei in the characiform family Gasteropelecidae. (2006): '' Fishes of the World'' (4th ed.). John Wiley & Sons, Inc. p.209 The scientific name means "''Sternoptyx''-subfamily", from '' Sternoptyx'' (the type genus) + the standard animal family suffix "-inae". It ultimately derives from Ancient Greek ''stérnon'' (στέρνον, "breast") + ''ptýx'' (πτύξ, "a fold/crease") + Latin ''forma'' ("external form"), the Greek part in reference to the thorax shape of marine hatchetfishes.

Freshwater Hatchetfish
The freshwater hatchetfish are a family, Gasteropelecidae, of ray-finned fish from South and Central America. The common hatchetfish is the most popular member among fish keeping hobbyists. The family includes three genera: '' Carnegiella'' (four species), '' Gasteropelecus'' (three species), and '' Thoracocharax'' (two species). Distribution and habitat Freshwater hatchetfish originate from Panama and South America (though they are absent from Chile). They tend to be an upper-level fish, often swimming directly below the surface of the water, biding their time patiently. Size When fully grown, freshwater hatchetfish range in size from 1 inch up to 2 1/2 inches. One exception is the Giant Hatchetfish Thoracocharax securis which can grow up to 3 1/2 inches. The smallest being the two species, the Pygmy hatchetfish Carnegiella myersi which only grows to about 0.9 inch (2.2 centimeters), the Dwarf Hatchetfish Carnegiella schereri which only grows to about 1 inch (2.6 cent ...
