Killifish are nice aquarium fish, they are tropical fish and dwell in freshwater. They are considered very aggressive fish, that’s why many aquarists look away whenever they are mentioned because they could either stress your other fish to death or even attack and kill them directly, and probably eat them. There are many types or species of Killifish, but they all seem aggressive or semi-aggressive, but there is one specie that is not considered to be aggressive, which is the Golden Wonder Killifish.
