Characins are a large group of fish with a great diversity in size and shape. They range in size from the tiny Bolivian Pygmy Blue Characin, at just over 1/2 inch, 0.67" (1.7 cm) to the gigantic Goliath Tigerfish Hydrocynus goliath at 4 1/3 feet (1.3 m). A few of the larger characins are important as food or game fish. Shapes range from round disc-type' fish like the Silver Dollar, elongated fish like the Pencilfish, to the Hatchetfish wiht a deep bodied 'hatchet' type shape.

The spotted hatchetfish, , is one of the biggest species and can reach up to 9cm/3.5" in length. Again, it is a silvery fish, though perhaps ashade more brilliant than the silver hatchet, and it is immediatelyrecognisable thanks to the pattern of small blue-grey spots on the backhalf of the body. Given its size and shape, this fish can be veryimpressive when kept in a decent sized group, and while not as commonlytraded as marble and silver hatchets, it is not too difficult toobtain. This species looks superb kept with things like angelfish anddiscus, but it could equally easily be kept with peaceful gouramis,climbing perch such as , clown loaches, orany other non-aggressive tankmate of suitable size. The spottedhatchetfish needs fairly soft, slightly acidic to neutral waterconditions and plenty of oxygen. It is a bit less forgiving than thesilver hatchetfish, and good filtration and plenty of water changesseem to be essential to long-term success with this species. A superbfish, to be sure, but one best suited to the more experiencedaquarist.The store labeled them blue hatchetfish and didn't know much about them. I could tell right away they were a cyprinid but the guy (not the main guy) at the shop, which I really like, told me it was probably related to hatchetfish or tetras.Argyropelecus hemigymnus, a deep sea hatchetfish, has photophores along the lower side of its body. These produce a dim blue light. A predator looking...Blue Hatchetfish Description: A delicate species that is on the endangered species list. Rarely available in the aquarium industry these days. Pristine water conditions are required because these fish are sensitive to water quality problems.Blue Hatchetfish Diet & Nutrition: Carnivorous - diet should include live insects and mosquito larvae but these fish will also accept protein based flake or pellet food. RANGE: Rare everywhere. The few examples have come mostly from the Gulf of Mexico, but at least one suspected Hatchet Marlin was caught off Dade County and others have been reported in past years from Cuba. If it is truly a species, it probably occurs wherever Atlantic Marlins are found.
HABITAT: The open seas.
DESCRIPTION: The Hatchet Marlin may simply be a variant of the White Marlin, but a difference in the scales lends credence to the belief that it might be a distinct species. The scales are round, whereas those of the other Marlins are pointed. Coloration is similar to the other Marlins, but closer to the White than to the Blue in body proportions. The name comes from the dorsal fin, which does not dip in the manner of the Blue and White, but tapers gradually to the rear, outlining a fin that's intermediate in size between those of the other Marlins and the Sailfish.
SIZE: Uncertain; possibly to 200 pounds or more.
FOOD VALUE: If you catch one, save it for science!
GAME QUALITIES:Probably same as the White.
TACKLE AND BAITS: See White Marlin or Sailfish.
