These are tiny fish, ontario average is only 3 inches. Are they really that aggressive? Mine are in with cichlids and not aggressive at all. Salvini and jewel are worse.

I always thought these guys were big brutes.

They arent as aggressive as central american cichlids eh? More like a JD
Males can be real aggressive , it depends on the individual, in my experience adult size can be anywhere from 2.5 to 17 inches, with average about 5-6 inches, they do well on koi food and in outdoor goldfish/koi ponds.
 
Most of the greenies I’ve kept have grown to around 10 inches and lived with some of my toughest fish, Jags, Doviis all sorts of Amphs. I usually catch them to use as dithers if my tank needs them. They are plenty tough enough, definitely not afraid and usually out eat my centrals, but that’s probably because they were wild caught. Maybe they grow slower in a colder climate, but in a heated tank they should pack it on. I would say that they are about as aggressive as an average Central American Cichlid.

A few of mine were about 2 pounds, note that some populations only get a few inches, these "dwarf" types seem to occur in tiny creeks
 
A 2 pounder is a real pig buddy. That’s impressive.
I'm convinced under the right conditions I could grow a bigger one, sadly there life expectancy is not long, most pure green sunfish seem to average about 7 years of life
