Most aggressive aquarium fish?

  • We are currently upgrading MFK. thanks! -neo
Since I like aggressive fish.. im gonna say, "channa micropeltes" (all sizes)
and some red bellies (piranhas).

Currently looking to get a serrasalmus rhombeus.. (black piranha)
 
What do you mean? Attacking your hand? Glass banging? Killing tankmates?
 
lol breeding convicts
 
I know someone over in Malasia that saved a Channa Micro from someone who was feeding it rice! It's not only in with his Koi, it hand feeds.!

I would have to say that it depends on the individual fish when it comes to aggression.

If I had to pick species, I would have to say Flowerhorn hands down.
