These fish belong to the class Actinopterygii and make their home in freshwater environments like ponds and swamps. They thrive in many habitats, showcasing their ability to adapt and survive.
Killifish love to munch on small insects, crustaceans, and even some plant matter. Their diet keeps them active and playful, darting around in search of their next tasty treat!
With a lifespan of about 1 to 3 years, killifish may be short-lived but they sure know how to make a splash during their time! These lively little fish remind us that big things can come in small packages.
