It's just a general rule of thumb Steve -- there are of course exceptions and it depends on probably a lot of variables and probably subject to debate (such as "why does my BTA no longer have bubble-tips" and so on .. ultimately we don't REALLY know). In this case though I think there is really very little question that the pictured anemone is
H. magnifica.. and a very nice coloured specimen at that.
I'd take that off your hands Namscam in a heartbeat if I didn't already have a 24" ritteri that fills an entire 72g, I think two would be kind of out of my means. LOL Good luck though it really is quite nice, if I was you I'd keep the anemone and get rid of the other stuff (or get another tank, that's what I did)
