Top 10 most aggressive freshwater fish

  • We are currently upgrading MFK. thanks! -neo
Fahaka puffer is definitely aggressive. I had him in a tank with a fire eel and he bit his face off the first night. Every time I walk by he attacks the glass trying to get at me!
 
a Great white shark wouldnt die, the convict would, why would a great white shark die in saltwater? its lives in the ocean!!

Haha I meant to say freshwater! Wow I feel stupid...
 
It all depends on personality I guess.....I know people who had elongatus piranhas who were no more aggressive then a neon tetra but mine is really aggressive
