Most Aggressive Fish you ever owned?

  • We are currently upgrading MFK. thanks! -neo
I have kept all sorts of large aggressive cichlids, but I had a male Convict that was insane. I bought it as a dither and it killed a 12" Midas and a 8" Flowerhorn, within 2 hours of me buying it. It was a cool fish, huge head and really pretty, long trailing fins. MY tank was all aggressive fish but his little fish was just insane.

I would have been pissed!!!
 
Shamu hands down! Any elongated fish less than 2-ft equals food!!

my old 6 inch midas killed a same sized parrot and was all ways nipping and taking chunks out of my old 14inch oscar
 
I had an african cichlid - red top zebra male. He killed all his tankmates, even fish that were much larger than he was. Fish was a crazy killer.
 
It's gotta be the electric catfish. These angry fat sausages are highly predatory, territorial, and just total bullies in general. On top of that, they have super powers. Other fish just don't even stand a chance.
