I use to keep them as pets in a relatively smaller tank. It was soooooooooooo worth it! We had a small catfish, small bass, and a crappie. It was so much fun to feed them and then create hiding places for them and watch them ambush bait or chill out. We would put crawdads in there as well but they never lasted too long. The main difficult task with it all was cleaning the tanks. A poorly managed tank will kill the fish pretty quick. Also don't forget to add the nutrients to improve the oxygen levels and other stuff that maximize the water conditions to make it liveable for the bass. We had so much fun buying a dozen gold fish and hand feeding them or what not. I'm sure you'll get responses discouraging you from keeping a bass, but just ignore it. Get yourself a small bass, put it in the tank, and have fun with your new best friend. Had somebody else caught that small bass, they might have eaten it, but you're givin that little feller another chance at life by wining and dining him with easy to catch food and admiration. Warning, they may not live longer than a year...so don't forget to get a new one immediately. Good luck.
