Well the problem is we normally advise having a tank established minimum of 6mo so it is stable enough, so I guess it depends how patient you are, though you could add corals that are attached to rock that is movable.
I have had to move many corals out of a nems path, if you are lucky enough to see that move coming.
The issue I see w/ BTA's over the years is often they will pick a spot, stay there a year, you feel certain they are done wandering and then they just pick up and move for seemingly no reason.
I don't keep BTA's myself anymore for this reason, not unless they are in a nem specific tank.
Some people do, and have luck in doing so, good for anyone that does.
I personally like less risk, so I have kept primarily sand dwellars, less wandering, and it's on sand bed if they do, though it is even more critical params be stable for those type of nems usually.
On my new tank however I'm going to try a mag/ritteri.
I'm hoping their need for strong light and flow will keep it perched high up where I place it, fingers crossed.
From my years of watching here it seems doable, but I would not consider them a beginner anemone.
