The Common Hatchetfish Gasteropelecus sternicla is an unusual shaped fish.The name "hatchetfish" is derived from the head of a hatchet."Hatchet-shaped belly" is what the term Gasteropelecus means.

The hatchetfishes leap from the water and fly through the air to catch insects.They are accepted as the only flying fish.A number of fish can leap out of the water, but only freshwater hatchetfish use their fins to aid their flight.

The Common Hatchetfish is also known as the River Hatchefish.The name Silver Hatchetfish isn't a good one as a couple of other species are also known by this common name.The Silver Hatchetfish Gasteropelecus levis is one of the species in the same genera.

The hatchetfish are similar in appearance, but different in size.Both the Common Hatchetfish and G. levis are small in the wild, reaching 1.5 and 1 inch, respectively.The Greater Hatchetfish is a full inch longer than the Common Hatchets.The Greater Hatchetfish doesn't have the black horizontal line that is seen on the Common Hatchettfish.The Common Hatchetfish is the one that is most popular with the hobbyist.

The freshwater hatchetfish feed on insects and crustaceans in the wild.With their mouths situated at the top of their bodies, they are used to eating surface foods.The Common Hatchetfish will eat all kinds of live, fresh, and flake foods as long as the food is on the surface of the water.Brine shrimp, fruit flies, and blood worms are good for keeping a good balance.

Aquarium CareHatchetfish are easy to care for once they are acclimatized.Aquariums are closed and need some maintenance.There is a build up of nitrates, organic matter, andphosphates in the water.If the tank is densely stocked, water should be replaced on a regular basis.The water should be replaced at least 25% of the time.

The fish are hardy.A school of 6 or more fish will do best in a 15 to 20 gallon aquarium.They feed at the surface of the water.They eat at the surface so some clear areas need to be provided.The fish is likely to jump out of the tank if given the chance.Ich is a problem when these freshwater hatchetfish are first introduced to an aquarium.Before being placed in their permanent home, new specimen should be acclimatized in a quasar aquarium.The blackwater native is tolerant of both harder and more alkaline water.Water should be soft and acidic for them to thrive.The minimum tank size is 15 gal and can be used to house a school.The mouth is at the top of the body.

Common Hatchetfish are prone to developing infections.When they are first introduced to a new aquarium, this is especially true.Specimens that have just been acquired should be kept in a tank.If their tank water is not kept soft and acidic, they will be susceptible to ick.The freshwater hatchetfish are prone to skin flukes and other parasites.There are parasites (protozoa, worms, etc.).There are two types of infections: general infections andbacterial disease.Disease is not usually a problem in a well-maintained aquarium.There is no guarantee that you won't have to deal with health problems.Anything you add to your tank can introduce disease.Plants, substrate, and decorations can harborbacteria.Make sure to properly clean or suck anything that you add to an established tank so as not to upset the balance.If an outbreak of disease is dealt with at an early stage, it can be limited to just one or a few fishes.When keeping more sensitive types of fish, it is common for all of them to be exposed to the same disease before the first warning signs can be seen.The best way to prevent disease is to give your Common Hatchetfish a good environment and a balanced diet.The more closely their environment resembles their natural habitat, the less stress they will have, making them healthier and happier.Stressed fish are more likely to get sick.Aquarists should be aware of tank diseases.It's important to know the signs and treat them early.Aquarium fish diseases and treatments can be found here.
