I'm kind getting tired of the peaceful nature of my fish's, I still like them but I want to get something agressive and carnivorous (in it's own separate tank of course).
Problem here you see, is with my still being in high school and parents deciding really what kind of tank I can and can't get, I unfortunately can't get a 150g piranha tank or even a 55g really.
I just got a new 38g planted, and I can't get anything over 20g now for this predator.
So, my question is,
Is there such a thing as an agressive, carnivorous, monster predator that can go in a 20 gallon or less sized tank long-term? Cold-water or tropical, freshwater or brackish. Just as long as it's not marine.

Them little puffas really lay the smack down pretty much on anything. My Black River Puffer will literally bite the head off of anything put in with it.
