Hearing “Clown Knife” can conjur up some pretty freaky thoughts, but these fish aren’t scary. What is scary is how they’ve become one of the most invasive species in the world. This species has been introduced in rivers and lakes through out Asia and even parts of Florida. Growing to over 3 feet long, there isn’t much they can’t outcompete and they are able to quickly establish themselves, taking over the new habitat.
