I've had all sorts of fish in my aquarium(s) over the years. In addition to "tropical" fish bought in a store, I've also played host to green sunfish, rock bass, bluegills, crappie, largemouth bass, smallmouth bass, channel catfish, northern pike, walleye, tiger musky, and even sturgeon!! Oh...and also baby snapping turtles and other pond turtles.
I'm down to a single aquarium these days. Its a 125-gallon tank that is about 6' long.
I usually hosted these fish for up to a year before releasing them.
My question is... how big can you get a bluegill to grow in an aquarium? At a local boat dealer, they have a large aquarium with a couple of bluegills in it. They feed them minnows, and they have grown substantially in the past year. I didn't measure them, of course, but they appear to easily be in the 9" or better range.
Has anyone else tried to grow a bluegill(s) in a home aquarium?
