My BTA has moved very little in the several years I've had it. Maybe I got lucky, dunno. But I have read, and the current location of my BTA seems to corroborate, that they do like to situate themselves in a slight hollow/depression of the LR. If you have something like that, facing upwards towards the light that would help. Sounds like it's found a spot now though, so I wouldn't mess with it unless there's a danger of it encroaching a prize coral that might get stung. Never a sure thing with an anemone though, they sometimes just decide it's time to roam, regardless of what we do.
