So how do you feel about your stocking rate at this point?
This is a point of confusion to me.  Some say fewer fish, which conventional wisdom tells us, but I see a lot of talk about "spreading aggression"
I am planning (ie: saving money) for a large aquarium purchase/set up.  Probably in the neighborhood of yours, between 100 and 150 gallons.  I want to have a variety of different native sunfish, probably 1 specimen from 5-6 species (Bluegill, Shellcracker/redear/whatever, green sunfish, yellow perch, warmouth....).  I would also like a black crappie, a black bullhead and a grass pickerel.  
These fish should all reach a similar size I believe and I dont want any huge size advantages in my tank.  I would love to keep a largemouth more than anything, but Im not prepared to house a fish like that long term.  I think these fish on my list could live peacefully together as long as nobody is small enough to be prey and I dont have territory issues.  
Several of these fish can be aggressive, but I think having many different species should help that some, rather than a gang of one fish.  Im not entirely sure.  So I am curious what your outlook would be on your current stocking rate if you werent planning to build a tank big enough to park a car in.
