Scientific name explanations

Why use scientific names?

Ah, those scary scientific names that keep popping up everywhere! Although at first it can be a little overwhelming to use, they are very important when you need information on a specific type of fish. Some fish have been in the hobby for so long with the same name that it really doesn't seem important to know the scientific name because when you tell someone that you have a guppy or a molly they immediately know what fish you are talking about. However as you stray away from the more common fish you will find that more then one fish can have the same common name or some fish that have multiple "common" names depending on what store you are in. This is when the usage of the scientific name becomes very important so people will know which fish you are talking about.
Even though most people recognize the importance of using scientific names for their fish, they can be challenging to figure out and remember. Most of the scientific names are derived from the Latin language, then just to make life a little more confusing they will also through in the occasional Greek word for you! However if you have a basic understanding of what some of these terms translates to it'll be easier to either identify the fish, why they are classed together and possibly some of their habits. Hopefully this listing will help you sort out these Latin names a little easier!

Taxonomy Family Tree:

Every living thing has it's own unique identity. To make it simpler for scientists to identify different living creatures they are divided into different groupings. Here is an example of all the full name for the Neon Tetra.

Neon tetra, Paracheirodon innesi
Neon tetra, Paracheirodon innesi

Kingdom: Animal
Phylum: Chordata (with a spine)
Sub-phylum: Vertebrata (with a backbone)

Sub Order: Characoidei (Denotes that the fish are Characins)

Sub-family: Tetragonopterinae (Tetras)
Genus: Paracheirodon (Closely related species)
Species: innesi (the specifics for the individual animal)
Sub-species:

When referring to a fish, it's necessary to give both the genus and species names in order for people to know which fish you are talking about.

The genus name

Is unique to a group of closely related species, however it's possible to have two of the same species names provided they aren't in the same genus. Convention also says that scientific names should be italicized. Genus name is always capitalized and species name is always lowercase to differentiate between the two names.

Here is a list of the more common terms used in the scientific names of fishes. Becoming familiar with these terms and their meanings can be an aid to identifying unknown fish.
For example if a fish has lots of stripes then searching for a species name containing multifasciatus or fasciatus which means many stripes or striped. Such descriptive names are often used.
