Would having a green sunfish in a 180 gallon stop it from being aggressive toward fish like a black crappie or other peaceful fish?
 
I was going to buy one, but i wanted to make sure if the green sunfish would be ok with the black crappie. My black crappie is about 3-4 inches, my 3 bluegills are 3-4 inches, 3-4 inches, 4.5-5.5 inches. My longear is about the same size or smaller than my largest bluegill. My warmouth is about 2 inches and he will move in as soon as he grows more. I know that greens are agressive, but on another website, i was told that they are only like that for a little bit before they are full adult. by the way, i do not care how colorful they are, i still like their shape etc. and are cute.
(this is coming from the guy who thinks common carp and frog fish are cute by the way)

What they told you isn't true. Mine was aggressive his whole life. The temperature of the water can really make a difference though. If you keep the water cooler, he will be less aggressive, but if its warmer, he may begin to think its spring and try to build a nest and defend it. My advice would be to have enough cover to where he could claim a piece as his own. My green had a fake stump that was hollow inside that he loved and would sit in it until he could no longer fit into it.
 
would he be aggressive at 72 F? It will fluctuate between 75-68 degrees. is there a better fish that is like a bass that is not a green or a warmouth?
 
I have never hear of warmouths being very aggressive. I usually hear readbrest and greens are. There are exceptions to the common thought of agression though. By the way, are bluegills suppose to have red fins? mine had red fins for almost the whole time i have had them, but i only pics without red fins. I got them from http://www.aquaculturestore.com/
 
I really think the aggression has more to do with territory. I've kept a couple and it seemed that if they were able to claim a territory and defend it then they would be less aggressive, but if there isn't enough structure then I think you'll run into more problems. I don't think you'll be able to get rid of all aggression entirely, that's a risk you'll run with greens, but I think you can lower the aggression level by giving the tank a lot of structure.
