Tropical Fish Information You Need to Know – All About Classification

posted in: Aquarium & Fish | 0

In this report on tropical fish information you will hear about the origins of tropical fish keeping, its background and the scientific naming formula that classifies the fish.

Background
There are a growing number of people who keep tropical fish in an aquarium as it becomes more popular and the age of these aquarists varies from youngsters to the more elderly. Tropical fish need more looking after cold water fish such as the goldfish and it is this additional caring factor that I believe attractions folk to tropical fish.

Because tropical fish are smaller you can have more of them in your tank, they are more colorful in most cases, there are more species around so you have a lot to choose from and you can easily purchase the fishes without them having to be bought in from their original habitat as they are now mostly bred in captivity.

Because of the particular rearing that has been carried out over the years it is improbable that the fish you have in your aquarium will be the same coloration, size and shape of the original fish from, for example, Venezuela, where the checkered dwarf cichlid originated , but where breeding in captivity has been unsuccessful then you will have the authentic wild stock imported.

The Naming System
Pretty much every fish species has a common name (even several), which pet shops and aquarium keepers may employ on a regular basis, but if an correct description and identification is needed then common names are not adequate.

Carl Linnaeus was from Swedish and a physician, botanist and zoologist (known as the father of modern taxonomy and considered to be one of the leading lights of modern ecology) who laid the building blocks for the naming of species system called the binomial nomenclature scheme.

A relationship among groups of animals & plants has been used for over 350 years and is identified and established by the binomial nomenclature system. The subject of finding, describing and ordering organizations has seven major sectors and is known as Taxonomy, in this order, Kingdom / Phylum / Division / Class / Order / Family / Genus / Species.

However, as its name suggests, the binomial nomenclature process only uses the last two identifiers, the genus and the species names. Although each term in the name is in Latin and it could be known as the 'Latin name', biologists have a preference for calling it the 'scientific name'.

Two scientific names for a fish can happen now and again due to the re-classification of a specific fish. This is as a result of advances in Ichthyology (the study of fish) and the fact that this new name is not universally picked up by all concerned.

In the event that there is no specific descriptor for the fish of a known genus then the scientific name would be the generic name (the genus) with species added on. In January 2010 information from a major fish database showed that fish species numbered over 31,000 and that 250 new species are registered annually. Fish species outnumber all the remaining vertebrates (mammals, birds, reptiles and amphibians).
