'Carpe Diem' does not mean 'fish of the day'!

Often the mere sight of Latin combined into pairs of tongue twisting scientific names laid out before the hobbyist will cause them, if unfamiliar with this form of organization, to recoil in horror or at best throw up their hands in exasperation. That said, this form of classification remains the best we have and is often useful in getting the basics right for the care of a certain fish. In an attempt to help, we present here an introductory guide to catfish families. The descending order of this list loosely corresponds to the availability of the species. Notes are given about some of the features used to tell different families apart, click here if you need some help with these anatomical terms. In addition if you're not too sure about classification (terms like family, species, genus etc) click here. For an excellent introduction / overview, check out this article, failing all that, try the glossary.
