I have a 129 gal tank that used to be my daughters before she went to college, which, in the beginning, housed a full size Oscar (12" or so), a Texas ciclid, a Jack Dempsey, a firemouth and a convict. And a pleco, which is now pretty large. All that is left now is the Jack, which is now full sized (about 8") and I am trying to figure out what else I could put in there. Any ideas?
