I've been told it's a Rose Bubble Tip Anenome (RTBA), but the tips of the tentacles don't bubble up like some I've seen. Maybe just a Rose Tip Anenome, then. As far as how hardy it is, I got it from a guy who had it for five years, and I've had it for about two. It survived my 'newbie' phase and has split several times. My thoughts are that's it pretty hardy---given good water quality and lighting. For lights I have 130 watts PC 50/50 (2-65 watt bulbs) and it does fine. Some think its not enough, but I really can't afford much more, and it's doing fine.
