It's pretty. Not much out there on this, but it is still an Entacmaea quadricolor. To appeal to the part of you that is "good with science", my 2 cents is that anemones can be temperamental creatures. But then again so can my cat. In the wild anemones have lifespans that are measured in decades not months. So for someone who is not aware of their parameter swings etc, I agree this would be a very bad choice. In my old tank back in 1996, I had two btas that I added after only a few weeks following cycling. At that time I was running a 90 gallon with power compact fluorescents, very low tech and they lasted in that tank for 16 years quite happily. I ended up moving to Vancouver so had to sell/give them away. I have just recently, as of 8 months ago, I set up a new tank (40G) that is anemone dominant. Currently there are 3 btas, 8 mini maxi carpets (Stichodactyla tapetum) and 9 rock flower anemones (Epicystis crucifer). They all have their spots and as often anemones do, found where in the tank they like it best. With the exception of one of the MMC, they have all pretty much stayed near where I first placed them. Most of them went in after a cycle with dry rock and I believe I used Bio-spira as well. I now have better lights with the new LED technology out there. They are all doing very well, I feed 1-2x a week, chunks of a raw seafood mix I get at the grocery store with frozen octopus, clams etc. Though do beware of other slower-moving inverts, the other day I had a $60 superman rhodactis mushroom detach and was carried right into the larger carpet and it was gone in minutes.
I say as long as you read up and research these fascinating animals you should be just fine. If you search on YT, Than from Tidal Gardens did an episode on anemones and he found 2 of them living in a huge sump/mixing tub, quite happily attached to the hot water pipes and they are as happy as pigs in ... I guess just don't get mad at them when they decide that sitting nicely at the front of the tank is not for them and they vanish to the back. Acclimate slowly via drip, turn off all pumps, ideally in the evening, put them where you would like it to live and keep your fingers crossed it stays there.

Wishing you the best with your new venture. After all... "with fronds like these, who needs anemones"!
Oh, DO get something to cover powerhead intakes etc.
But hey, I cannot keep Xenia to save my life.
