Appearance & SizeĪs far as size goes, Killifish are on the smaller end of the spectrum. If it weren’t for their exceptional ability to adapt over time, this species would not have survived. Left in the wild, this number can be as short as 6 months to a year when living in extreme conditions that dry up the freshwater streams during that region’s dry season (more on this later). With the proper care and right tank conditions, the average Killifish lifespan will typically fall within the 2 to 5 year range when living in a well-kept aquarium. Fortunately, the Dutch term killi or killy in Killifish refers to the fish’s preferred habitat in low lying channels, sleepy streams or within a ditch.

Some potential owners are scared off by its seemingly dangerous name. Found naturally in still or moving freshwater streams, these fish get the shade they want from overhanging trees or lush overgrowth from lower-lying bushes and other vegetation along the shorelines. These fish prefer sub-tropical water and somewhat shaded light, but some can survive in other water conditions. However, these fish are not native to Northern Europe, Antarctica or Australia. Killifish are also found in parts of Asia, Southern Europe, throughout Africa and even into the Middle East countries. They are almost startlingly bright and lavishly shaded and can be found in freshwater or sometimes more brackish streams and rivers from parts of Canada all the way down through the Americas into Argentina.

These interesting fish have stunning color hues and patterns, and most of them can be described as tranquil with an overall good nature. Unlike those other species, this fish is generally not included in the freshwater aquarium inventory sold at local fish stores. The Killifish is a proud member of the Cyprinodontidae family, and these vibrant and colorful freshwater fish are distantly related to guppies, swordtails, platies, and molly fish.
