I have an empty 55gal 13"x48" and I don't know what to do with it. I'm not even sure of what all of my options are. I'm leaning towards a lone green sunfish unless someone can talk me into something else. I'm not a huge fan of the whole wetpet idea, I just love the personality of a green, who doesn't? Haha. I'm assuming there's no way to keep a green with anything in a 55 safely. My last green was a monster.
