Wandering anemone

It's an old problem I know, just got a lovely light green bubble tip
anemone, but he cause trouble on his first night in the tank.
Currently he is sitting bang in the middle of a bunch of pulse coral
heads, and you can tell the coral is not at all pleased with the
situation. I like anemones, but have never had much luck with them,
losing them in powerheads previously, currently we have none in this
tank! Fishing him out from amongst the coral would I think do more
damage than any it's suffered already. I just hope he moves on again.
Anybody got any training tips for these things - or do they just go
where they will regardless?
