Pound for Pound toughest fish?

  • We are currently upgrading MFK. thanks! -neo
nastiest fish i've ever seen is a 2 inch Jewel that I owned for a little while, he killed a Jack dempsey almost twice his size. also if invertabrates are allowed a big mantis shrimp woulld be king of the tank (e.g Peacock)
 
hopalias AIMARA. Pretty much a giant scaley beast with a vicious aggression.
 
No one mentioned that alba alba knife fish, that supposedly can't be kept with any other fish, because they are so nasty...Imagine if they were grew as big as a clown knife? could be trouble
 
That diplo is about 9 inches
N it can grow about 27 inches
Still juveniles but teeth shows its predatory level:):):):):):D:D

My moneys on a Brevis tiger fish, theyve been observed feeding on larger prey by amputating the tail and letting it die then feeding at the surface
