That still pretty much describes them all. Most of the time I'm not too sure which is which when I'm dealing with Apons. I consider Apons to be disposable plants anyway so I'm not too conserned at which ones I have. I can get a package of 6-8 Apon bulbs at Wal-mart for $2.67. When they get nasty or over take my tank or need rest I take them out toss them and add another 4-5 packages and call it good.
