What is the pencil?

pencil pencil is a freshwater fish found throughout South America. Known scientifically as nannostomus is commonly used as an aquarium due to its color and shape. They are relatively small, ranging from one to two to two inches (2.5 - 5.1 cm). Earth like Colombia, Venezuela, Bolivia and Brazil keep a strong market on these types. Although the pencil traditionally occurs in these areas, Asia climate has also been adapted. Today they are found almost all over the world because of their use in aquariums. It was found to be apocryphal because all fish are basically identical. Today, scientists have found that there are simply 17 different species include the Nanostomus genus, in particular nannostomus Beckfordi and nanostomus harrison , which is used in the trade.

depending on the diversity of pencil fish, coloring and patterns differ significantly. Many have black or brown horizontal stripes with armor of gold or silver. Others have different stains covering their bodies.The sausages of different species are usually lively colored and can come in almost any shadow. These fins can be long or short depending on gender and species.

While the original populations of South America knew about pencil, it was not added to scientific records until 1872. General scientists have seen the existence and types of species through drawings and writings for years. Until 1933, however, real fish photographs were published in scientific journals. William T. InNES was a photographer, known widely by his work on taxonomy. Over the years, different species have often been wrong with different types of genera, but in 1975 they were merged into the united family nanostomus .

Pisces The fish is best maintained in aquariums with a temperature range of 72 ° F (about 22 ° C) to 82 ° F (about 28 ° C). Although they can be used as general community fish, they benefit the fastest when they are associated with other types of the sameo rodu. Owners of these fish should feed animals browse and algae and also maintain aquatic plants in tanks to help with oxygen production.
