As we get closer to Halloween, you are probably asking yourself “are there any black and orange catfish?” It is a great question, and there are indeed lots of black and orange catfish species (depending somewhat on how you define black or orange and on the color/pattern/age/health of the individual catfish in question).

Corydoras aeneus (wild coloration)

One definitive answer however can be found in the friendliest and most adorable genus of catfish the adorable Corydoruses (which are the subject of some of Ferrebeekeeper’s fondest and saddest aquarium memories). Anyway, Corydoras catfish are noteworthy for their tiny size, sociability, schooling instinct, and endearing features. Perhaps the most popular species of Corydoras catfish is Corydoras aeneus, “the bronze corydoras” a dish which reproduces easily in aquariums and is thus sold in vast quantities for the pet trade. A mild mannered generalist of robust health and easy-going nature, Corydoras aeneus has everything that a hobbyist could want…except for bright colors. In the wild the fish is a sort of demure brownish green with translucent gray edges.

Since Corydoras aeneus reproduces so readily in captivity, however, catfish fanciers have started to select for brighter colors, and thus we have Corydoras aeneus “Venezuela” a domesticated breed of tiny tropical catfish which is black and orange so as to make it more appealing as an ornamental fish. If the fact that there are people who spend their lives working on selectively breeding fish to be flashy shade of orange and black is shocking to you, I will have to introduce you to goldfish!
