Hello! I'm doing a speech on fish(to satisfy Speech 101 in college) and I was just wondering if there are more aggressive brackish/saltwater fish than there are aggressive freshwater fish. As far as what you would put in an aquarium. thanks for your help!!

Saltwater fish are definatly more aggressive! even clownfish won't allow other clownfish in the tank when they are breeding (which is just about always if you have a breeding pair) The corals themselves wont let other corals near them.

i have had puffer fish before, and found out firsthand that they are aggressive, but other than one molly I had, I haven't found any other aggressive freshwater fish. But I've noticed that when you move into brackish and saltwater aquariums, it seems most of the fish are aggressive. I just didn't know if I was overlooking anything or not. Thanks for your help!
