Top 10 most aggressive non-cichlid freshwater fish?

  • We are currently upgrading MFK. thanks! -neo
i've had piranha, gars, clownknife, giant snakehead, bichers and from the fish i've keeped the snakehead tops them all, by far. i've never seen another fish so aggressive and intent on killing everything else around it
 
Clarias catfish- I had a 35cm one that loved to fight, Saratoga, killed a big jag and was starting to pick on my 80cm rtc that's wen I got rid of it, but still was a top hard fish to have.
 
Asian RTC
Senegal Bichir
Betta Fish
Common Pleco (when they want to be)
 
Aggresive topline that I know : Full grown tiger oscar, which can confront and stare down any other aggresive preditory fish in the tank like snakehead, gar, ancient fish, arowana, pike, piranha, electrical eel, blood parrot, firemouth, tilapia, , , et al. I guess oscar, blood parrot, firemouth and tilaia are from the ciclid family tree?
