Understanding Fish Names
From Shirlie Sharpe,
Your Guide to Freshwater Aquariums.
What’s In a Name?
Ever find yourself among fish enthusiasts who use scientific names and felt foolish because you didn’t know them yourself? Don’t feel too out of the loop - even long time fish owners don't always know the scientific name of their fish. Scientific names are in Latin, which isn’t exactly short and sweet. If that isn't bad enough, names frequently change due to new research and discoveries that alter their classification. Furthermore, it’s not unusual to see erroneous labeling at the point of sale, especially in shops that don't specialize in fish.
So don’t lament too much over not knowing scientific names. On the other hand, if you want to learn more about your fish, knowing the proper scientific name is invaluable.
It isn't all that tough to learn the basic classifications of fish, and you might even find yourself getting hooked on it.
Classification
You might remember studying the major groups (phyla) of the animal kingdom in school. All fish are of the phylum Chordata, which interestingly enough includes birds. The phyla is broken down into classes, which in turn are broken down into orders, which are further broken down into families. Families are broken down into genus, which in turn are broken down into species, and finally (if necessary) broken down into varieties (see graphic to the right).
There are roughly 10,000 of species of freshwater fish, but less than 200 of them are commonly seen in aquarium stores. In fact a mere 20 species of fish make up nearly 90% of all aquarium fish sales. Generally speaking, commercially available fish fall into the following seven groups:
Anabantidae - Gourami, Betta
Cichlidae - Angelfish, Cichlids, Discus, Oscars
Characiformes - Tetras, Silver Dollars, Pencilfish, Hachetfish, Headstanders, Piranha
Cypriniformes - Barbs, Danios, Rasboras, Loaches, Goldfish
Cyprinodontiformes - Killifish
Poeciliiodae - Livebearers (Guppy, Swords, Mollys, Platys)
Siluriformes - Catfish
Family and Genus
Fish in the same family usually have some general similarities. Fish in the same genus have even more similarities. Because fish are given a scientific name that is based on the genus and species, you can easily determine which fish are in the same genus. For example, the scientific name for the fish commonly known as the Blue Gourami is Trichogaster trichopterus, which means it belongs to the genus Trichogaster. Several other gouramis, such as the Moonlight, Pearl, and Snakeskin gourami, have a scientific name that also begins with Trichogaster, which means they all belong to the same genus.
So where do you begin learning scientific names? Start by learning the scientific names of the fish you already have, or are most interested in having. If you are searching for fish information, you'll find it is a lot easier if you use the scientific name rather than the common name. Here is a list of common fish names that also shows their scientific name. If you can’t find your fish on the list, send me an email and I’ll help you find the proper name.
