I'm glad to see that their others on this board who are into native fish. A couple of decades ago, I kept largemouth bass, bluegills, warmouth, green sunfish, pumpkinseed, etc, at one time or another in small 10 and 20 gallon aquariums. All of these fish tend not to like company and are best kept by themselves if housed in such small tanks. If people knew what great pets these fish made, the fish stores would be in trouble. All of the aforementioned fish (all members of the sunfish family) tame down quite well and will take food from your hand after they get used to you. Bass can even be taught to jump a few inches oout of the water to grab a minnow from your hands. These fish will also let you touch them. These fish will also look at you as walk around the room.
Now I'm setting up a 180 gallon tank and I can't wait to stock it. I'm thinking of trying to have one each of a largemouth, spotted, and smallmouth bass in the the 4 to 8" range. Or I might see if I can just get one each of each of the sunfish family - real small ones. What I end up keeping will depend how they all get along.
